When I was looking after a friends elderly parents I had the same problem. One of the things they didn't want was meals on wheels as they didn't like the food. There was another place that did a similar thing 3 day a week and we split the meals so they lasted longer. As they got older and sicker the sight of a large meal was a real turn off. Sometimes having the main meal for lunch helped and then they had desert for tea. Just be careful of putting to many meals in their freezer, for some reason it can also be a turnoff. The meals you do are great as they are easy to eat. Keep up the good work and know they appreciate all you do for them.
