Nestled in pita bread, Middle Eastern falafel is draped with Spicy Tahini Sauce.
Place half the chickpeas in the bowl of a food processor; pulse until chopped. Set aside in a bowl. Place remaining chickpeas, garlic, onion, parsley, cilantro, coriander, cumin, paprika, salt, lemon juice, and tahini in food processor; process until a coarse paste is formed, about 30 seconds. Add to bowl of chopped chickpeas; add egg, flour, and sesame seeds. Stir until combined. Shape into 12 two-inch patties.
Heat oil in a large skillet set over medium heat. Add patties; cook until golden brown, 3 to 4 minutes per side. Remove from oil; place on a paper-towel-lined tray.
Fill pitas with lettuce, tomato, onion, and falafel. Drizzle with tahini sauce; serve.
