Some of our veggie favorites:
Spoodles -- huge selection of appetizers and salads. At least one veggie entree, usually one not listed, and they will take meat or fish out of a couple of others
Cape May -- great salads, veggie dishes, chef has always made us a veggie pasta dish if the pasta on the buffet has meat in it. Usually have on truly vegetarian soup.
Tusker House buffet - huge selection of veggie dishes
Counter Service:
DHS - Grilled sandwich at Backlot, pizza and ceasar salad at Pizza Planet
Epcot -- Many selections at Sunshine Seasons in the Land pavilion, including cuban sandwich, lo mein, fried rice, stir fried veggies, packaged salads, and usually one of the soups is truly vegetarian (no meat stock)
Epcot - Tangerine cafe has great tabouleh, hummus, and more
MK - veggie chili and veggie sandwich at Columbia Harbor House
MK -- veggie egg rolls in Adventureland
AK - only thing I know of is pizza and ceasar salad at Pizzafari
boardwalk bakery - grilled veggie panini
There are many more options, but these are places we seem to go back to on every trip.
For instance, there are veggie wraps at the Electric Umbrella in Epcot (not bad) and one at Cosmic Ray's in MK (tasteless). But others may like these.
One other note! You can get a veggie burger in just about any place that offers regular burgers, even if you don't see it on the menu, just ask. I don't like veggie burgers, but my kids and DH do.
