I admit there are evenings when I just don't feel like cooking at all--although a lot of the time I then realize it would be more effort/time to hop in the car and get takeout. I also admit that if I lived in a city and had good takeout options like decent Chinese within a 5 or 10 minute walk, I'd probably get takeout more.
I've been mostly working at home (or traveling) for years now but when I was going into an office, a had a repertoire of quick and easy weeknight meals--and others that I could make on weekends and give me one or two meals of leftovers.
I enjoy cooking a lot (which can be parsed two ways and I mean both of them) but of course I feel like that sometimes too.
But once you're into it, that's simple, those are the nights you have leftovers, something from the freezer (made before), or 10-15min pasta & grilled vegetables.
(To be honest my problem is more not feeling like that often enough, so I always make something new and the freezer fills up. Also eating from the freezer comes with the problem of not remembering exactly what you did, if it's particularly good and you want it again...)
