In a food processor, pulse together chickpeas, scallions, and cilantro until a coarse paste forms. Pulse in flour, egg, and salt. Heat 1/4 inch olive oil in a large skillet over medium high. Add chickpea mixture to skillet, 1/4 cup at a time, pressing to form patties. Cook until golden brown on both sides, turning once, 4 to 5 minutes. Serve with salad and lemon wedges.
