Budget recipes?

I'm working on paying student loans and other debts, as well as moving away from fast food. Living by myself, and I have a few kitchen appliances I can use.

Smallish crockpot, toaster oven, small air fryer, various pots and pans, and the good ol toaster and microwave. (Hoping to avoid using the oven, work hours are long and don't have a lot of freetime on my days off.)

Does anyone have cheap and/or quick meal ideas I could make? And maybe take-along meals I can eat on the road? (Work as a delivery driver.)

Bonus points if I can share the food with my dog, leftovers tend to go uneaten.

Thanks!!
