I buy chicken thighs or chick cutlets when I'm low on money. If you're tired of chicken, I buy these
They're pretty cheap at WalMart.I just put some buffalo sauce and cook it in a pan. Then with that I make 4 bowls with rice, black beans, vegetables on top. You can try Butterball Turkey Bacon I see the packets at the store 2 for 5. The Jenni-O brand of turkey bacon is more expensive.
Also at WalMart they have small bags of Tilapia for like 7. I think there's 8 fillets in the bag. If you're dead broke cans of tuna are like 59 cents. I make it with greek yogurt and throw some carrots, peas, and corn in there and mix up then eat it in a leaf of lettuce. I think you can't eat too much tuna though cause of mercury.
If you look in the meat section they'll have some labeled managers special that are a little cheaper cause they're closer to the expiration date. Just look at the meat to make sure it's not brown or gray. I'll buy it and cook it the same day.
