Cook at your place. In your grocer's freezer you'll find some frozen vegetarian dishes - name escapes me - they come in a soft plastic bag like Celetano raviolis do. "Foods of the World" or something like that. They're composed of rice and vegetables and different spices. My favorite is the Moroccoan. The Aztec is a close 2nd with the Indian being a bit stinky to cook (what with all that curry flavoring). All 3 are good, but I listed them by preference.
I'm not a vegan but the stuff makes for a pretty easy meal to do when I've already had burgers, chicken, pizza, and pasta for the last 3 days straight. The downside is that I can only cook them on the nights my wife is out of the house because she can't stand the smell of the Indian dish.
If you're in a rush, do KFC corn, biscuits, 'taters, and gravy, with a salad.
