These stores go beyond the fried chicken, pork chop and lasagna meal. They have many varieties of fish, steak, veal, chicken meals. In the upscale store they have Filet Mignon steaks already cooked. They must know they are going to sell them if they are confident enough to cook them in advance.
Yeah I’ve seen them, my favorite store’s butcher counter has some. The websites have anywhere from 50 to a couple thousand options to chose from.
Actually probably most of them are made from food about to expire. It’s a good way to add a week of storage, and you get to charge more. Win win.
