Baked Falafel

Preheat 400. Place garbanzo beans, parsley, garlic, cumin, coriander, salt, and baking soda in blender. Process until the mixture is coarsely pureed. Mix garbanzo bean mixture and onion together in a bowl. Stir in the flour and egg. Shape mixture into four large patties and let stand for 15 minutes. Heat olive oil in a large, oven-safe skillet over medium-high heat. Place the patties in the skillet; cook until golden brown, about 3 minutes on each side. Transfer skillet to the preheated oven and bake until heated through, about 10 minutes. Serve with tzatziki sauce.
