Meanwhile, puree garbanzo beans, 2 ounces cheese, garlic, 1 tablespoon olive oil and cumin in processor until smooth. Season with cayenne pepper and salt and pepper to taste. Transfer puree to small bowl. (Can be prepared 1 day ahead. Cover and refrigerate.) Heat 1 tablespoon olive oil in heavy medium skillet over medium heat. Add lamb and sauté until cooked through and brown, breaking up with fork, about 5 minutes. Drain all fat from skillet. Season lamb with allspice, oregano and salt and pepper. Brush bottom side of 1 pita round with olive oil. Place on work surface, oil side down. Blend 1/4 cup bean puree with 1/4 (about 1/2 cup scant) of lamb mixture. Spread on pita.
