With a little determination, you can actually cook pasta in a microwave and it doesn't come out too badly. I got one of these gimmicky things but I'm sure you don't actually need this exact thing. https://www.amazon.com/Rapid-Microwave-Macaroni-Dishwasher-Safe-Microwaveable/dp/B08XS5PHFK then just add whatever sauce you want and maybe some microwaved veggies.

You should also get into making sandwiches, snack plates, and salads if you like those, if you're willing to put in a little extra effort or nicer ingredients they'll easily be better than dining hall food.
