What are some quick, easy and cheap meals for a college student?

I'm a college student going to school full time and working two jobs. As you can imagine I am super busy and do not have a lot of time to cook, nor do I really know how haha. I was wondering if anyone has any quick and easy...oh and cheap! recipes that they enjoy making. I'm a little picky, I don't like spicy foods or fish but I love pastas and cheesy dishes! I have a crock pot, vegetable steamer, and a George Foreman grill. I love cooking in the crock pot because it's very easy and can cook while I'm at school so if anyone has favorite crock pot meals I would love that. Feel free to share any of your go-to recipes! Thanks!
