These last few suggestions are perfect. Other "picnic" like foods that he can eat over a few days: pasta salad (either you make it or get from a deli) or other roast vegetable salad, roast chicken or fried chicken pieces that can be warmed up a piece at a time or eaten cold, the makings for hot fudge sundaes or something simple that he can have when he wants? Baked macaroni and cheese with instructions on how to microwave a portion at a time?

I wouldn't so much worry about it now if his family is around. Wait a month and monthly invite him to eat with your family and send him home with left overs or make a dish for him to just warm up.

16:10 here, Wegmans or Whole Foods can put together a nice meal for him that he can heat up in microwave as needed. You are a good person OP.

What about something that he can eat over a few days time - like potato salad, whole roast chicken and string beans? Maybe a nice apple pie too?

OP here -- I am not really that nice but this man is so wonderful and kind that I wish there was more that I could do. He has family in the area but I'm not sure if they're staying with him. It would be nice to get him enough to share or to have several nights of good food for himself. And yeah, I picture him eating mildly old-fashioned kinds of food like what my grandparents would have eaten, though I really have no idea. He's African-American, not that that detail matters -- I just want to get him something that he will enjoy.

OP, I just wanted to say how kind you are to do this. Your post made me think of my grandfather, who ate filet mignon and microwaved creamed spinach every night after my grandmother passed away b/c it was the only thing he knew how to cook. When we realized what was going on, my aunt went to visit and teach him some new recipes.

I don't have experience with any companies other than Allen Brothers, which tends to be pretty pricy, but I found this link: http://www.thedailymeal.com/16-best-mail-order-food-companies Some of the companies listed will deliver heat-and-serve meals

OP, that's really nice of you. Do you think he'll have to be feeding others (visitors), or just himself?

A sweet and wonderful neighbor has lost his wife. I want to provide a meal or two and would ideally order a nice all-inclusive dinner through the mail (like Harrington ham or something along those lines) that would be easy for him to warm and serve. Any ideas?
