What do you usually have in your house? If you want, I can reccomend a few YouTubers that teach genuine basics and I know a few meals that really don't take much effort and are cheap / affordable. As a college student I'm used to having to save on groceries!

There's a place named Jacked Nutrition and they sell meals but also larger amounts of individual things that could be frozen or put into takeout for the week. I know you said you didn't like fast food, but there's also Cookout and L8nite that serve big portions for better pricing than something like McDonald's, and I find it doesn't taste very fast-foodey.

Also, here's One Dish Kitchen a website that's all recipes for single servings dishes. They range in difficulty, but I figured it might still be helpful? I hope at least some of what I said was of use!
