I really don't have any different ideas for meals but I do have a suggestion/warning for you. I was makig and freezing meals for my MIL in addition to buying her the soups and other canned food that she liked. It took me awhile to figure out that she was no longer able to figure out the microwave and was putting the food out for feral cats that roamed around her house. When I was cleaning out her house after she went into an assisted living situation, I found 5 pans that she had burned food to a black crisp in and tossed under the kitchen sink. So try to assess how he is doing with those kinds of task as he continues to age. Good luck in your search.
