Today I made veggie stock with some random veggies and veggie bits.
When I was done, I decided to make use of those veggies. I put them in the chopper, and put the bits in a bowl, I added wheat gluten, nutritional yeast, breadcrumbs, soy sauce and some seasonings to taste....oh and black beans! I pressed them into 'burgers' and cooked a big batch to freeze. They are actually quite tasty. The seitan holds them together and it's a good way to sneak in some veggies.
I got about 16 burgers out of 2 and a quarter cups of wheat gluten. and a bunch of veggies and bread crumbs.
