There are a lot of those services popping up all over the country, under different names. I think they sound interesting, but I would never use one. I enjoy the process of cooking. Either I want the pleasure of choosing my own ingredients and chopping, etc, or I want to be served something already made. But that's just me
I think they have become really popular!
I'm not sure, but I think all of those places create recipes for batches that serve 4/6/8 etc. If any of them offered single serving recipes/containers, then I could see a benefit from that. Create your own diet frozen dinners
