Sweet Tomatoes, yum.
Tofu noodle bowl at Hollywood Brown Derby. (the cobb salad without the meat was just lettuce mush, FYI)
Both soups (french onion and potato leek soup) at Be Our Guest are vegetarian.
Vegetarian chili and Lighthouse sandwich at Columbia Harbour House are so good. Weird combo. But equally good.
Tusker House lunch and dinner...might not be worth the cost *to me*, but if a character meal is on the menu, that's the one we want.
The Wave breakfast buffet. Request the Tillamook smoked cheddar (suitable for vegetarians) grits withOUT the bacon. They have made it special for me each time upon request.
Beware cupcakes and other desserts...Disney quite often makes them with gelatin. Avoid (my strategy) or ask for ingredients.
All counter services have menu binders that you can request to look at.
The apple slush drink in New Fantasyland has a "marshmallow" topping, but it's NOT actually marshmallow. I looked in their ingredients book. It's just a syrup with that flavor.
