I'm 24, just got a new job and need your help /r/budgetfood

So after a year if eating tuna fish or various lunch meats for lunch every day I really need a change of pace. I also had some downtime between jobs due to the former job being so slow so I need frugal but filling dinners. Unfortunately, I do not have time to cook both in one night, so I need foods that can be eaten for dinner and then leftovers taken to work in the morning.

I have a range and a microwave, and at work we have microwaves. also at home i have a blender and a food processor * I have an 8" or 10" frying pan, a similar size/depth cast iron pan, various pots * a healthy number of seasonings though nothing particularly uncommon * and I would like to try to keep my food costs below $80 a week * rice cannot be involved in any of these recipes unless it is rice crispies as a coating or whatnot. it makes me extremely ill when fried/steamed/etc. * I am not looking for salad recipes unfortunately as I have many but after eating them for dinner so frequently I need something with more protein.

Thank you guys in advance!

edit: added "a week" per u/emconnors
