There are various kinds of foods that are already preserved in one way or another that you could use. The most-preserved ones could be saved for the last days (...maybe you could put big notes on each saying which day they're for, or even numbered 1-10 with breakfast, lunch or dinner, or leave him a note for what to eat every day?). Preserved foods have usually been dried, smoked, or fermented...or they're in vinegar, brined/have a lot of salt, or have a lot of sugar (all ways that foods have been preserved over history). Here are some foods that will last a long time or at least 10 days in the frig, or even in the cabinet, and even sandwiches can be frozen. Perhaps you could just have someone deliver a one-time load of stuff from your freezer to his frig, for those last days? DAIRY ...yogurt, cheeses, butter ...even sour cream and cottage cheese (especially the individual serving containers ...and milk if it's bought with a late date and kept in a cold area of the frig FRUITS: whole fruits dried fruits canned fruits for awhile even open (buy in heavy syrup for extra sugar) apple sauce GRAINS: cereals breads batter breads like banana bread, brownies, cupcakes, danishes, cookies, etc crackers, pretzels, graham crackers, etc. VEGGIES: bags of salad, coleslaw, etc carrots dried "chip" veggies dried soybeans or other veggies from Whole Foods or Asian markets MEATS + PROTEIN smoked salmon cooked bacon ham jerky dried sausages cold cuts (the ones with lots of preservatives) hardboiled eggs (in shell) OTHER: peanut butter and jelly pickles, pickled veggies nuts mayo, and almost all regular condiments including chutneys If he will open cans, that would increase the options a lot too, even if he won't heat them. For example, he could open an individual can of tuna then dump ketchup or mustard in it, etc. Vienna sausages in cans are reasonable, and there are other meats in cans, as well as fruits, veggies that wouldn't be bad cold, etc. Also, he might be willing just to take a bowl or plate of something out of the freezer and ONLY HAVE TO put in the FRIG for the next night, but which time it should be nice defrosted. (I guess he'll be eating only cold or room temp foods the whole 10 days if he won't even use the microwave.) Will come back in a minute maybe with more. . . .
