We joined a service called Better Meals out of Vancouver, Canada.
They offer free delivery with $30.00 minimum order to my parent’s house from an extensive menu. Cost is only CAD $7.50 / meal. Unbelievably inexpensive for what you get.
Main course with two side dishes. Soup. And dessert.

Everything arrives frozen in recyclable containers. You can heat in the over or microwave.
You’d need trial and error to find the dishes you like best.
For example, my Mom liked the Turkey dinner but did not like one of the chicken dinners.
For those not going out much, Better Meals saves shopping. Cooking. And cleaning.
You could store some of the meals in the freezer, only pulling something out when it turns out you don’t have time to cook for yourself.
I’d recommend Better Meals. It’s available to anyone. They deliver only certain days of the week depending on where you live in B.C.
Note that the food comes without seasonings. You’d add those to taste.
