You can make up a whole crap ton of spaghetti with garlic bread for like $10. Feed your family and have left overs for a couple days. Easiest shit in the world to make. Don't insult your family with fast food.
First of all, how the hell can you hate spaghetti? That's just wrong.
Second, what do you like? You can get a 3 pound bag of chicken from wally world for like 5 bucks. sack of potatoes for a few dollars. loaf of french bread for a dollar. bag of frozen veggies for a couple bucks.
So you can have grilled chicken, mashed potatoes, veggies, and halfway decent bread for 10-12 bucks. You can cook a lot of stuff on the cheap.
Get a big package of hamburger, some buns, some chips, and some dip for like 10 bucks. Make real burgers. Make a shit ton of pancakes and bacon and eggs. Make homemade macaroni and cheese. make some meat loaf and mashed potatoes. I could easily go on.
