Well put down that takeout menu. The New York Times put together a great list of meal suggestions that can each be thrown together in about ten minutes. I guarantee that if you love food, you won't be able to read this list without salivating.
Not all of the ideas are easy, and not all of them are low-calorie. They are all, however, much better for you than that Kung Pao Chicken you were just going to order.
UPDATE: Damn you, New York Times. Apparently you now need a Times Select membership to download the article. That's OK -- you can either sign up for a free 2-week membership or just ask me to email you the article directly.
