I cook because it's cheaper than eating out. But the trade-off is the time I spend researching and preparing healthy and diverse meals. I'm only feeding myself and fresh food goes bad quickly, so I also don't have the benefits of scale. The problem is, currently you can only pick two out of cheap, good and quick.
So a better product which solves a real problem needs to nail all three. It needs to be cheap, good (fresh, healthy and diverse) and quick.
Being quick involves subsidizing not only the meal prep but also the research involved in making good choices. Properly educating consumers on basic nutrition and using graphic labels to encode nutritional information at a glance.
Being good means sourcing fresh meat and vegetables. Properly flash freezing, separating, storing and shipping meals to maximize longevity and the area covered by each commissary kitchen.
Being cheap is the hard part. First, you and your shareholders have to be willing to put the consumer first. as Bezos did with Amazon. Profits are a side-effect of maximum efficiency, but the baseline is whether the customer is happy with the product.
You also have to reduce waste as much as possible by streamlining recipes and ingredients and measuring portions precisely. Reduce plastic use. If you ship meals with special packaging like refrigerants, encourage monthly rebates for customers who ship them back out in bulk.
It's not a hard problem, the issue is that of funding. Shareholders expect a certain margin or eventual buyout whereas the food industry has notoriously low margins to begin with. Existing convenience meal businesses tackle the higher end market as a result. But the convenience meal lifestyle is slowly becoming a necessity across demographics, and a company which tackles this issue smartly and aims for sub-$5 meals, and offers great bulk prices for monthly memberships, and is willing to not be raking in billions, will come out on top.
