Hello. Sorry I'm just now getting back to you regarding the Morningstar products. There aren't any that are "allowed" per se. I just picked ones that were lowest in fat and carb content (spicy black bean burger wasn't too bad and pretty much the only one I liked). If you don't mind veggie burgers, I believe the original boca burger was the best choice, but it's been a while since I've purchased any of these as I have stopped being vegetarian and now just buy all organic animal products. Good luck!
