Reddit mentions of Justin's Classic Peanut Butter Squeeze Packs, Only Two Ingredients, Gluten-free, Non-GMO, Responsibly Sourced, Pack of 10 (1.15oz each)

I keep a Quest bar in my purse just for this reason. If you're trying to avoid artificial sweeteners, a bag of nuts or snack tube of peanut butter can save the day as well.

Chin up! Snickers Ice Cream is a dirty, dirty mistress!

I think I figured it out.
step 1: eat packet of peanut butter
step 2: talk to female
step 3: ??
step 4: profit!

You could eat crackers, jerky, trail mix, fruit, and supplement the crackers/ fruit (apples and bananas) with individual packets of peanut butter like this: https://www.amazon.com/Butter-Justins-Ingredients-Gluten-free-Responsibly/dp/B00E1XPY3A/ref=mp_s_a_1_11?keywords=nut+butter+individual+packets&qid=1567406938&s=gateway&sprefix=nut+butter+indi&sr=8-11

I also second Budget Bytes, her website is great! She has pictures explaining every step of a recipe. She also did a SNAP Challenge so you could save that much more money if you wanted to. I'm a fan of her black bean quesadillas, which isn't so much cooking as cracking open cans and packages of shredded cheese, tortillas, and spice containers. The only real cooking to do is toasting the quesadillas. You could even get through this recipe without using a knife! You can buy frozen chopped onions or fresh chopped onion from the salad section of the grocery store. You can get around cutting the cilantro by using scissors, and they sell jars of minced garlic, too. The recipe takes 2 cups of shredded cheese which is how much is in one bag of shredded cheese.

Sorry for the wordy reply. Hope this helps!!

It sounds like you're an awesome host. The bread is a great idea, and very thoughtful.

As for cross contamination if you don't want to worry about keeping a whole separate jar of peanut butter safe there are Justin's squeeze packs in regular peanut butter and various other nuts and flavors. I think stores like Whole Foods sell them individually too.

Also a lot of gluten free bread is much better toasted so it might be worth getting some toaster bags for your cousin to use. I've never used them before but my nutritionist recommended them.

I guess this advice pretty much hinges on how much your guest likes peanut butter, but PB sandwiches (or sadwiches, as I call them) are pretty much my go to food when I have to carry food around with me and I've had enough Kind bars.

Ditch the Powerade and carry some electrolyte powder you can mix into a water bottle instead if you're worried about replenishing electrolytes. It won't save a lot of weight, but when ounces count, 2 pounds can make a difference (1 gallon is 128 fluid ounces and weighs 8.34 pounds, 32 ounces is 1/4 of that and 1/4 of 8.34 pounds is 2.085 pounds).

I'd also ditch all but 1 (maybe 2) of the emergency blankets. They're great for what they are, but 8 of them is excessive.

Open the pack of Bic lighters. Throw the packaging away and stow the lighters in the backpack.

I also wouldn't carry a jar of peanut butter. Well, I wouldn't carry any amount of peanut butter, but I also wouldn't carry a jar of anything if I could avoid it. Too bulky. I'd look for something like this. If you want to match the caloric content of your jar of peanut butter, 11.42 packets of this stuff will get you there, and can be stashed around your pack wherever it will fit instead of having a big ass jar of peanut butter just sitting there.

I make my own dehydrated boil in bag meals. I use THIS SITE as a template and just modify things as needed. I use a lot of powdered heavy cream, powdered eggs, powdered coconut milk, powdered cheese (all purchasable off amazon), instead of rice I dehdyrate cauliflower rice in my dehydrator.

It requires a bit of experimentation on your part since they don't translate 100% but I've made some good meals, bag tacos, butter chicken, fajitas, pizza casserole, buffalo chicken casserole, breakfast scrambles, cheeseburger casserole, etc. I've been playing around with the idea of trying to make a few keto cobblers.

Portion them out into quart freezer bags with smaller bags for spices/seasonings, when time comes to eat boil a bit of water, dump it in the bag and seal it up, let it sit for 10 minutes or so wrapped in a handkerchief or something then enjoy.

If you are dehydrating yourself you want to use LOW FAT meats. I know that's counter-intuitive for keto but high fat content foods won't dehydrate right, so use lean cuts, then add fat later (heavy cream powder, etc)

here's the DEHYDRATOR I use

Here is the HEAVY CREAM POWDER

COCONUT MILK POWDER

CHEESE POWDER

EGG POWDER


I've priced everything out and for a day's worth of meals I'm around 10 bucks or so, vs Mountain House which are 5-8 bucks a meal and the Next Mile meals keto offerings which can be 15 bucks PER meal


EDIT:

You can also bring mayo packets with you and I like bringing Individual Justin's Peanut Butter Packs also, great way to up the fat and to eat "quickly" between meals.

I dehydrate my own jerky as a snack, also you can hit Walmart and get single serve individual foil packs of tuna and spam, they work good as a quick meal without having to boil water.

The above discussion about not needing to get calories from fat when at maintenance notwithstanding, if you need a quick way to get some calories, you could think about packing some of this in your luggage/briefcase/whatever. Small, portable, and an easy way to get a quick shot of calories.

Lactose is a dairy thing. My youngest daughter and my dog are lactose intolerant. I'm well acquainted with the diet. :P

They both enjoy peanut butter often. I keep these around as a quick snack for them. I like the almond butter versions better. They're a nice pick me up when you don't want Gu or other performance gels. Also, those little baby food pouches of pureed fruits and vegetables. They go down easy and digest well.

Here you go.

then you should be fully adapted by now. you probably won't even need it. i don't know where you live, but packs like these would be perfect and i've seen them at higher end supermarkets in the us. https://www.amazon.com/Justins-Peanut-Butter-Classic-Squeeze/dp/B00E1XPY3A/ref=sr_1_2_s_it?s=grocery&ie=UTF8&qid=1497293916&sr=1-2&keywords=individual+peanut+butter

How long does it take for you to run a 12k? I find food/gels should really be used if you're running something over 2 hrs.
My go to is a packet of Peanut Butter.
