One of my favorite subjects!
Premade chili 100000% is one of my favorites - and so easy! Last year I was looking to simplify breakfast so I brought a ton of egg whites from costco and made frittattas every morning - just add whatever veggies you want (onions, spinach, peppers, tomatoes, etc) and it can be different enough each day.
Burritos are also a staple for us. I'll put a silicone trivet in the bottom of a dutch oven (your 14 qt should work just fine), and heat it up slowly (don't forget to flip them)!
As for other premade meals:
This is one of my all time favorites - so simple but so delicious. You can dress it up however you want too and to make it even easier, substitute the whole tomatoes for Rotel, use boneless skinless chicken thighs instead of the whole chicken, add in some kale and you're golden! This freezes pretty damn well (potatoes get mildly mushy but that's fine).
Here's another dump and forget pressure cooker recipe I really like:
1 cup presoaked (15 min) drained white rice
2 cans rotel (I like hot, duh)
frozen veggies (I did corn and onions/peppers but you could also do spinach or kinda whatever you want)
chicken thighs (presear if you're feeling fancy)
cumin, onion powder, garlic powder, chili powder, sprinkle of salt
some salsa on top of the chicken thighs
Little bit of veggie/chx broth (not a ton, just a splash or two)
Seal, high pressure 7-8 minutes. Natural release. Remove and shred chicken, add back to stuff and mix it up. I have some other ideas on the spreadsheet I made for 2021's extra long trip you can view

camping oven which has actually been super handy for random things - Andrea even successfully made brownies in them one year!
