love the responses so far since i am in the same boat - looking for cheap veggie options.
So far we are planning on:
Sandwich of Earl caprese
Captain Cook's tonga toast
Starring Rolls Cafe (in Hollywood Studios) with bagels, pastries, coffee
Adventureland's Egg Roll stand (with vegetarian for $2)
Beaches & Cream veggie wraps & burgers
Animal Kingdom Picnic in the Park bag with veggie wraps
thinking about Wolfgang Puck express too now
