Brian, you can find a lot of easy, nutritious microwave dishes here:

I don't know how large your nuke is, but I even make chili and spaghetti sauce in mine.
I suggest you peruse the shelves of your supermarket for convenience foods.
I assume you know about Easy Mac...fix 2 pkgs, add a can of drained tuna for tuna casserole.
Rice-a-roni works great in the nuke, and you can make all kinds of creations with that... Steam a chicken breast, chop it in pieces, then add to the RR as it cooks. Add a can of drained vegies toward the last. Or buy a bag of broccoli & cauliflower florets with the baby carrots and toss handful of those in when you add the liquid. You could also use canned chicken to speed things up.
Or add shrimp, a can of chop suey vegies, and season with a bit of soy sauce.
The boxed Au Gratin and Scalloped potatoes are surprisingly tasty. Get a nice thick slice of Virginia ham from the deli, chunk it up, and cook in with the potatoes. A few florets of fresh broccoli or a small can of drained green beans and let them cook along, too.
If you like Cajun food, all of the Zatarains mixes can be done in the nuke.
Look into some of the good canned soups on the shelves, too. Cambell's Chunky and Progresso have some delicious soups that, with crackers and cheese, can stand as a meal on their own. The Chunky Chili comes in several flavors, and it's really good. Nuke some dogs to go with.
And don't forget Velveeta Cheese dip...mix it with Pace Piquante Sauce, nuke until melted, and use as a dip for raw vegies, chips, spoon in your chili, or drizzle on your dogs. I start with about 1 cup for 1 lb. of cheese. If it's too thick, add some more sauce and nuke a little more.
Really, the only thing I didn't have much success with was cooking dry pasta. I'm sure there's probably a method, though.
