Meals you make for yourself may be easy to make extra helpings of and put in freezer bags. Potatoes, meat, gravy, spaghetti, etc. It all freezers well in freezer bags. All he would have to do is remove from freezer, remove from the bag-or rip away the freezer bag if needed- and place on microwave safe plate. You could add a large square of wax paper in the freezer bag so he has something to cover the plate up with. He would be eating exactly what you are. A taste of home.
