As a college student, your thought processes are somewhat limited. Those four years of your life boil down to fit under a few small categories, most of which bring you grief somewhere along the way. They are, in no particular order; Academics, Finances, Social Life, and Food. Now I'm not a master scholar or financier, nor do I have what is considered an 'average' social life (My Friday nights primarily consist of stuffing my face with pizza while playing Dungeons & Dragons), but I have learned that college food brings tears to the eyes of many students(either while choking it down, or 45 minutes later in the bathroom). That being said, here's a few culinary options for the days when you want to dodge the commissary chow.
The Watney Potato Platter
Wash raw potatoes under cold water, puncture four to five times (failure to do so WILL result in exploding potatoes) microwave until soft and easily sliced in half with knife. Serve with salt, pepper, and/or ketchup. OR, if you happen to have access to more resources than a mini-fridge and a microwave, slice potatoes in half and put a slice of provolone cheese on each, microwave an additional minute to melt cheese. Garnish with bacon bits, scallions, or heart attack inducing amounts of sour cream. And maybe ketchup. Really can't go wrong with that stuff.
The Slightly-Less-Disappointing Microwave Burrito
Remove burritos from plastic bag. Let sit until thawed (or microwave defrost). Heat oil in the bottom of a saucepan, add thawed burritos. Cook 5-7 minutes on each side, or until golden brown. Drop some cheese on them and drown them in salsa, sour cream, cheap hot sauce.... Or ketchup. Just an idea. Someone tell me how it goes if you try it.
Dads' Leftover Macaroni Casserole Thingy
Boil and drain plain elbow macaroni, brown some ground beef, saute some onions, and crack open a jar of pasta sauce. Mix components and layer into a oven(or microwave-safe) dish with layers of cheese(preferably mozzarella or provolone) throughout. Throw in oven(or microwave) until cheese melts everything together. This stuff keeps and reheats well, so a good sized batch can get you through a couple days. Pairs well with Arnold Palmer Ice Tea/Lemonade, as well as an after dinner breathe mint. Especially if you plan on talking to anyone, those onions are some powerful stuff.
And yes, I realize all of these include the literal use of melted cheese. Cheese is like the duct tape of food, it brings other foods together in complementary ways.
