Kroger has an offering in at least 1 store as a pilot here like like what you described called one-step meal kits. There's definitely an upcharge but they're pretty good, very easy, healthier than TV dinners, and cheaper than getting takeout delivered.

They also have a new offering that's a bunch of containers of frozen things like shrimp and potatoes where you can pay one price by the lb and mix and match across 10-15 different options. It's nice if you want a flexible portion size, just cooking for 1-2, etc.
