From Everyday Wholesome Soup by Kim Wilson, this recipe makes a good quantity of burgers. They keep well in the refrigerator and reheat nicely on a skillet or in the oven.
- Mix all ingredients in a large bowl.
- Grind in 2-3 batches in a food processor (until well mixed but not pureed). Scrape sides of food processor frequently.
- Shape by hand into burgers and bake at 350 degrees for 25-30 minutes (flip once halfway through).
