Let me try: How about a variant of your "selling food to neighbors idea"? Build a platform where people can organize local "cooking clubs" (like meetup.com for cooking). You can find other people in your area who like to cook (sometimes) and everyone in the group makes a meal for the rest of the group, taking turns. That way, if and what is cooked is not your business (no regulation), you're just facilitating the meetups and schedules.
