I'm trying to come up with a really meat-like veggie burger using TVP. I've got the flavours down fine, and added some sauteed shredded carrot, onion and celery for crunch, along with some bread crumbs but I'm stumped on the binder. Nothing really wants to hold the rehydrated TVP together. I've tried blending a raw potato and then cooking it into glue - didn't work. My next step is an egg which I'll add reluctantly because I would prefer that this stays vegan. But if not, not. I'm also considering pulverized rolled oats along with the bread crumbs. Anyone come up with a solution to this? I'd like the burgers to be grillable - so they have to hold up until they've cooked through. This is a puzzle.
