For serving, use disposable plates and bowls. For the actual food prep, get things that are already cooked and/or chopped up, like bagged salad, rotisserie chicken, baby carrots, frozen burger patties, etc. These things usually cost a smidge more, but for you it's only temporary. Do you have anyone whose kitchen you can "borrow" one day a week? Go to that person's house and make things like soups, casseroles, etc. that you can then freeze in serving size portions. That way you can still use the microwave but YOU control the ingredients.
