1. Get a big freezer. It's really surprising how much delicious stuff you can make just from frozen stuff that can last you forever. Frozen food is also often more fresh and with microwave and air fryer the prep of anything frozen is actually not very difficult.
2. Outsource as much as possible. Often it's really hard to outcompete efficient kitchens. I don't mean order Uber eats or something but there's likely a place in your vicinity that does food prep where you can take your food containers and stock up for 2-3 days. You can even freeze some dishes.

Wife and I really did the math because we feared of becoming lazy and it makes absolutely zero economic sense to cook everything at home right now unless you want to treat yourself or live in a very economically unusual places where #2 is not accessible.
