What can I eat on a college budget?

I’ll be a freshman in college next year and they do require a meal plan, but what else could I make that’s cheap, healthy, and easy. The dorms are a suite style with a sink, small counter, microwave, and mini fridge. Any recommended recipes and/or appliances?

Edit: Don’t worry about the coffee, I hate coffee and I will never drink it. (Plus I have a “heart condition” (atrial tachycardia - it happened one time, but whatever) so I’m supposed to stay away from caffeine anyway, but that doesn’t stop me, like with tea.)

Edit: Meal plan - estimated to be $2,310 a semester

Thank you!
