You can make pasta in the microwave rather easily. Just go with something sturdier like Rigatoni, instead of something like Spaghetti or Angel Hair. Then just heat the sauce to go with it. You could either go with a basic red sauce, or maybe even do a Primavera with some fresh vegetables that have been lightly steamed for color and texture. There are a number of recipes for cheese sauces that can be made in the microwave if you look around online.
Rice is very easy in the microwave, just get the fast cooking parboiled stuff. I use chicken broth for the liquid instead of water, then toss the rice with some steamed fresh vegetable medley that's also been steamed for a bit - stuff like broccoli, red peppers, carrots, etc... You could make a vegetarian filling for burritos or enchiladas, then assemble your burritos and heat them through (top with enchilada sauce and cheese if you like) and accompany it with a fresh salad.
I suppose you could cook some ground beef or ground sausage in it too if you microwave it in short amounts, and toss the meat around each time so it cooks evenly - maybe make a ragu sauce and serve it over polenta that's also been cooked in the microwave.
Or cook a bunch of bacon and make a fresh salad with crumbled bacon on it and use the bacon drippings to make a dressing. You could hard boil your eggs in there too to cut up and crumble over the salad - maybe make a Cobb Salad.
