Slow cooker, one minute to dump in ingredients and go to work.  Dinner immediately when you get home.  Sandwiches.  Pre-sliced produce if you're really that lazy.  Canned.  Frozen to microwave.  Meal prep Sundays.  Probably millions of dinner on a dime + 30 minutes or less meals.  Hams don't cook because they'd have to clean their kitchen probably.
