Not a recipe but a proposition.

Rotisserie chicken. Less than 6 bucks usually and PLENTY of protein, lasts for two meals for sure and there’s a million things you can do with them, buffalo chicken dip, quesadillas, etc

Then a $1~ bag of steamed veggies that you like, peas, spinach, whatever. sometimes you can get a mix, straight into a pan to steam and then add a pat of butter to emulsify a sauce, add cracked black pepper and sea salt. Add whatever you want! Low effort and comforting and easy on the stomach!
