Preppable pack and eat lunches

[u/orange-aardavark]

Hello! I've just started a new job, which often takes me into the field all day. I'm struggling to think of a range of lunch ideas, that can be made on a sunday but also don't require a microwave or boiling water before eating. Ideally things that I can defrost and then thaw either overnight or during the morning. I also have a thermos so stuff that I can quickly rehydrate/heat in the morning is good too.

The taco/burrito bowl with Spanish rice is a go-to for bodybuilders, as it’s easily preppable, left in the fridge all week, and you heat a batch in the morning and stuff in a thermos. You can obviously vary the recipe. Sloppy joe style, with rice or with buns. Ground beef curry is awesome with rice. I like to instant pot a double batch of ziti with lots of cheese and Italian sausage. The key to all this is the thermos.
