Prepared frozen meals to order
For my aunt, who will soon be 80, I'd like to find a source for good, reasonably healthy prepared meals that she could heat up. She lives alone, so single servings would be great. She lives on Long Island. Thanks!
I've heard good things about Zone Diets-to-Go but haven't tried them. Check out the thread for Jenny Craig v. Nutrisystem because they discuss other meal delivery plans within the thread.
ETA: that thread is found under General Chowhounding Topics
Try calling your local Area Agency on Aging. Many of them will have lists of delivered frozen meal companies that cater to senior nutrition needs.
Over here on the opposite end of the country we have Meals on Wheels, which bring very reasonably priced meals to the elderly and disabled and check in on them every day. I agree with Beachmouse - there may be something similar in her area.
