I've found that people who don't cook regularly often overestimate how difficult it is to cook at home. Sure you can go big and cook extravagant meals that take loads of prep time and cook time, but you can also saute some fish filets and some vegetables in 20 minutes start to finish - and most of that time you're still free to do other things around the house.
Of course this advice might not apply in a 400 sq. ft. NYC studio without two burners and room for two pans, but for most people that's not the issue.
