Buying "Clean" foods and budgeting

[h2s]

I'm serious...just can never diet properly...because of my weird sleep and work sched. I'm Trying to lose fat and gain strength/lean muscle mass...and I feel without the diet..I'm not going to make any progress. also...its hard for me to buy fresh...alot of it is so expensive compared to junk

Tilapia
Tuna
Brown rice
Bagels
Chicken
Lean ground beef

Buy the above in quantity and it is cheap and very clean.
