We reviewed Jenny and NS and hated them both.
BUT we didn't try the frozen dinners (unless Suzanne did on her own). I have heard that the upscale version is pretty good. But we didn't like the standard meals with the soups, etc. We got a pizza from NS that was moldy. I'm serious!
Purfoods is high $$ to do all day. They all are pretty expensive... But breakfast is so easy, that one is easily replaced, and often lunch is pretty easy to do. Maybe a partial day would be an option for you? Purfoods lets you order single meals. The other plans do require a larger order.
