what fast food places sell veggie burgers?!
Char Hut I think sells Morningstar veggie burgers. Burger King (but I've always hated them anyway) has veggie burgers. Dunno what brand. Many places have salads. McDonalds has veggie burgers outside the US (they probably have select places in the US but I don't know of any.).
Burger King has a pretty good one. And some Five Guys have veggie burgers . . .I think Jack in the Box may have one, but I'm not sure.
Burger King offers a vegetarian "burger"
