I also have a lot of food allergies.

Keeping meals simple has helped me a lot (not just from an allergy perspective, but diet adherence, time management, etc.) Most of our meals we build around one main protein and 1-2 vegetable side dishes.

I've found searching paleo and whole30 type recipe sites and books helpful for inspiration. While some recipes will be too high carb (or need to be modified) it gives you a lot of basics to start with.

For my carb eating husband I might withhold some of the fat from my meal and add it only to my portion, or make cauliflower rice for me and regular rice for him, or serve my sauce over vegetables instead of noodles. If you keep the carb mostly separate (rice, pasta, potatoes, starchy veg) it is easy to make it work for everyone.

Our primary vegetable side dish rotation is broccoli, green beans, leafy greens (spinach especially), asparagus, cauliflower, snap peas, squash, mushrooms, bell peppers, and brussels sprouts. I often buy 2 or 3 large bags of vegetables per week and mix and match into our meals, then do something different the next week.

For the meats I do a lot of chicken (roasted, fried, stir fried, curried, grilled,) pork (pulled with home made BBQ sauce, roasted, grilled, fried), burgers (beef, turkey, or beyond beef soy/gluten free pea protein), steaks, beef stew (with lots of mushroom and smaller amounts of lower carb starchy veg such as rutabaga), sausages (pork, beef, turkey, or chicken), ground beef (taco salad, stuffed peppers), and sometimes fish (usually just tuna or white fish tacos.)

Some substitutions you might make (but I'm not a doctor so check with yours):

• [Soured coconut milk]
  (http://www.nourishingmeals.com/2014/01/homemade-dairy-free-sour-cream-nut-free.html) instead of sour cream
  
  
• [Coconut aminos]
  (https://www.amazon.com/Coconut-Secret-Organic-Soy-Free-Seasoning/dp/B003XB5LMU?th=1) instead of soy sauce.
  
  
• I believe all (or at least many) [Daiya]
  (http://daiyafoods.com/) products are soy and gluten free. Some (like the cheese) are reasonably keto friendly, some (like the yogurt) are not.
  
  
• [Soy free veganaise]
  (http://followyourheart.com/products/soy-free-3/) can be used in place of mayo. There are a lot of options for [making your own]
  (http://www.seriouseats.com/2012/01/how-to-make-vegan-mayonnaise-mayo.html) as well. I love making chicken and tuna salads with this.
  
  
• Coconut milk for drinking and canned coconut milk for creaming things makes an excellent dairy alternative.
  
  
• For creamer I use [this stuff]
  (http://www.questnutrition.com/protein-powders/mct-oil-powder/) but it contains a little sodium caseinate so may be unsuitable for you. There's commercial coconut milk based creamers, or you can just add coconut milk and doctor it up how you like.
  
  
• Skip the eggs and eat the meat for breakfast. Bacon, sausage, and smoked salmon are all good. I buy the applegate brand breakfast sausages and all the ones I've had so far have been soy/gluten free and very good. I also like [flaxseed porridge.]
  (https://www.charliefoundation.org/resources-and-tools/find-recipes-home/breakfasts/item/1108-porridge) (substitute refined coconut oil or butter flavored coconut oil or spread.) Or you can make a low carb protein shake or smoothie if you're into that. (Or just eat food that's not "breakfast food.")
  
  
• There are many keto-friendly sweet recipes that make use of things like ground flax seed and coconut flour and shreds. One lazy dessert I actually love is heated up culinary coconut milk (until it thickens) with sweetener and a pinch of cinnamon. I eat it like rice pudding without the rice. I also like cold chia seed pudding with coconut cream and vanilla.
  
  
• You can get bulk sweeteners (sucralose, stevia, whatever you like) in liquid or powder form to avoid any bulking agents that add carbs and may be irritating.
  
  
• I find that taking a daily probiotic is helpful personally, along with eating fermented or cultured foods. There are a lot of non-dairy probiotic supplements.
  
  
• For snacks, pickles, olives, and raw vegetables! You can definitely find some soy free jerky, and there's also [epic meat protein bars]
  (https://epicbar.com/bars-overview) which are soy and gluten free.
  
  
• For my body, I find [MCT oil]
  (https://www.amazon.com/All-Natural-Coconut-MCT-Oil/dp/B00XB5IWJC/) and coconut oil the best choices for this as they may be more easily absorbed. Start with a small amount and work up though, as they can trigger diarrhea in some people.
