Any man who can't cook is a fool wasting his money. There are so many easy dishes you can cook, and they'll help you avoid buying fast food which will literally save your hundreds of dollars.
Some easy mode stuff:
-mixed veggies: quickly cooked. Or you can throw them in a skillet and saute them
-potatoes: baked, mashed, hash browns, whatever. throw some garlic in there for extra flavor
-skinless boneless chicken breast: you can get them frozen or not. cook on the stove
-fish: tilapia is easy, but there are others too. bake in the oven
-spinach: easy as hell.
Starter kit:
-Olive oil
-butter or substitute
-garlic
-garlic salt (tends to have less sodium than regular salt)
-pepper
