Cook for him. Chicken, hamburger, eggs can be scrambled or hard boiled - fruits & veggies you know he likes. I do up a whole crockpot of chicken with sweet potato & carrots & divide it out into meal portions after it cools enough. I also steam up a whole bag of frozen green beans at a time, so that's ready to serve. When we have steamed squash for dinner, I do enough for 3-4 days for Lucy also.
