Foods/ingredients that freezes well for meal prep to be later cooked/warmed for single servings?

My apartment is dorm-sized. I can’t do much in it, however i do have a tiny kitchen. A friend has lent me their apartment while they’re on vacation. I have the privilege of a full kitchen until the end of this week. I would like to maximize use of it with meal preps that i can freeze and later pop in the microwave or airfryer when i’m back home. I would really appreciate suggestions.

For example so far i have: Mac n cheese Meatballs Bolognese Fried rice (very plain, no egg no onion bc freezing) Lasaga Onion soup Cream of anything soup Taquitos

Currently i have use of an airfryer, toaster, instant pot, and vacuum sealer. These appliances are mine, but have been in storage since I couldnt use it. You can see why i must make the most of this opportunity. Any tips and suggestions and very much welcome. Essentially i just want to make a bunch of “lunchables” to leave in the freezer, so i can still have a meal even if i only have a microwave or a tiny airfryer.
