if you could get the toaster oven I would, I use mine all the time. healthy meals;
beans and rice, (spice it up, I add cumin, chipotle seasoning, etc)
stove top ratatouille
veggie hash, (zucs, summer squash, eggplant, green beans, mushrooms corn off the cob, sauted in olive oil and a touch of butter) anything really! with rice.
Go for the toster oven I cook for four in mine only thing I dont is large things like turkey's large chickens . but most anything else I use my toaster oven. Saves from heating up my large oven saves on the $$..
But, I guess you could do thing like sub sandwitches if you dont mind the mircowave effects on bread. quesadiea(sp spanish not my strong point) or as my kids used to call them mexican cheese sandwitches.
Use a microwave safe dish for chicken or fish fillet, which you dab with a bit of EVOO, salt and pepper, then some sort of flavoring. I like to use citrus - orange, lemon or lime - which flavors nicely. Slice thin and use as both a bed and a topping. Or sprinkle with some herbs, or a seasoned flavoring mix, such as lemon pepper seasoning, cajun seasoning, etc. You can marinate the chicken in EVOO, rosemary and garlic, or an oil and vinegar salad dressing. Cover the chicken or fish with wax paper and nuke until done. A side salad, a fresh veggie such as carrots or broccoli which you also microwave, crusty bread of some sort.
If you are only cooking for one, do a search on recipes for one person.
