Almost 2 out of 3 U.S. schools now offer vegetarian fare for lunch on a regular basis, according to a new nationwide survey by the School Nutrition Association. That's a nearly 40 percent increase since 2003, the first year veggie meals were tallied.

And we're not talking succotash and carrot and raisin salad, either. Most common vegetarian lunches include entree salads, veggie pizza with whole grain crust, rice and beans, vegetable hoagies, and lentil sauce with pasta, according to the nutrition group.
