I work at houston's on the grill and have watched for about two months how the veg burger is made. I don't have all the ingredients but the core. First of all everything is fresh not canned (no canned beets or canned pikcle jalapenos) the beets are freshly steamed and jalapenos are raw seeds removed and small dice, no eggs are used hence the word veggie burger. the sauce is a sweet soy sauce that does not consist of barbie Q sauce and you need to add rasins, and bulgar wheat. add this should get you a little closer.
good luck
