I think that's the main vision behind Travis Kalanick's CloudKitchens since he left Uber. You could order food prep for your week from a choice of menus, and the food would be prepared in an industrial kitchen for you and thousands of other people around you. It's basically restaurant-quality food that you can eat at home and isn't frozen.
Unfortunately for the meal prep market, I believe the break-even point for scale is much more difficult to achieve. Food is like hardware but with a much shorter end-of-life. You would need consistency in ordering to avoid excess spoilage and to operate at scale within small geographical pockets to make the delivery worthwhile. I really believe this could work with the right demographics and in the right geography, it's just much harder than simply delivering takeaways.
