This is the Veggie Burger from page 101 of Vegan With a Vengeance. It is beyond. I've tried a few veg burgers from scratch, and coagulation is the biggest issue that I've had with them. They tend to fall apart when you cook them and more so when you try to eat them. This one is a hint loose, but sticks into a patty far better than any other recipe that I've tried.
It has AMAZING flavor, and makes at least 6 burgers. I shredded the carrot, then chopped it a bit, and used white buns from Trader Joe's that were a perfect compliment (kind of a big, rustic bun). Toasted, natch.
