There are so many out there--I don't know where to start! I've tried Amy's California burger and like it--I also like Morningstar Farms Grillers and Philly Cheesesteak veggie burgers, though I can't identify half of the ingredients on the package which makes me a bit nervous...and Morningstar Farms Harvest Burgers are good, but only when warm. Once they've cooled they somehow morph into complete nastiness. Anyway, which other varieties are winners? Thanks!
