Preheat the oven to 400°F.

Place the garbanzo beans, tahini, breadcrumbs, egg, spinach, onions, cilantro, lemon juice, olive oil, garlic, cumin, coriander, and salt in a food processor. Pulse until the garbanzo beans are mostly smooth. Do not over process – a few chunks are fine.

Scoop the mix into a bowl and fold in the roasted red peppers, feta, and olives.

Spray a cookie sheet well with the pan spray. Shape the mix into 6 equally sized patties, flattening slightly, and place on the cookie sheet.

Bake the burgers in the oven for 20 minutes. Use a spatula to flip the burgers and continue to cook for an additional 20 minutes, until golden brown.

Serve on a toasted burger bun with lettuce, tomato, and tzatziki sauce if desired. May also be served with Once Again Tahini-Lemon Dressing & Dipping Sauce.
