I'm omnivorous, here, but I try to pack some healthier options whenever I can. Of course, I say that but what I do end up bringing still has a pretty high carbohydrate content (I can't get over my love of rice and noodles as a staple food).

In addition to beans and lentils (preferably with a combination of a grain to help balance out your amino acid profile), I recommend not being afraid of adding healthy fats to your food because it'll keep you sated for longer, and if you're careful about calorie watching, is more dense. In practice: I like avocados, and I use the keto trick of adding some coconut oil to airplane coffee to add fat to my breakfast.

Find ways to add fiber and proteins, secondly, to your meal considerations because both will help you feel full, like healthy fats will. Low-sodium jerky, trail mix, and protein/fiber bars are my usual no-refrigeration go-tos for those. Carbs are still necessary, but if possible get them from veggies, and you'll get nutrients to boot. Carrots, celery, broccoli, and grape tomatoes are my usual mainstays because they keep well in not-ideal coolers--especially paired with some dressing to add some fat content to your snacking.

If you don't mind using some of your layover/rest time preparing your meals for the next day and you don't want to be stuck with just the hotel microwave (if it's even provided) I recommend--like others--investing in a HotLogic Mini. I recommend going to their website to buy it because they often have sales. Your other fellow flight attendants occasionally get coupon codes for them, too, if you ask around; and sometimes they offer a BOGO Free deal. Depending on how you meal-prep (for curries, pilafs, ratatouille, etc I just cut up veggies and proteins into a Ziploc bag and spice the bag) it's as easy as putting it all in a Pyrex glass container (one of the HotLogic sets come with a glass container) and plugging the HotLogic in. Recipes that work in a crock pot work best in it, in my opinion. I've also used the Joseph Joseph M-Cuisine Cooking Set to cook during layovers, and I prefer it when I'm making pasta, noodles, or rice dishes.

To keep food warm, I've been using an insulated lunch pail like the Zojirushi Mr. Bento as a complement to my cooler. The inner containers can keep food hot/cold for around 8-12 hours while the top container typically remains at room temperature. It's a little thing, but having a hot meal in-between a long 12-hour day with no time to buy expensive airport food is a wonderful way to keep your morale up.
