What things did Grayson bring Maniac to make the apartment more comfortable?

From the text:

By the time they got back to the baseball room, they were nearly frozen. But the freeze was good, for it made the warmth of the little apartment all the more welcome. Within fifteen minutes the space heater had the place positively tropical, while in the toaster oven their five-pound Thanksgiving chicken was already beginning to brown. A pair of hot plates and a squad of pots were pressed into action, and by mid afternoon the two were sitting down to a feast of roast chicken, gravy, cranberry sauce, applesauce, SpaghettiOs, raisins, pumpkin pie, and butterscotch Krimpets.
