Step 1: To make the sauce: whisk sauce ingredients (yogurt - salt) together and then set aside.
Step 2: To make the sandwiches: in a food processor add the onion and cilantro and plus until finely chopped (about 10-12 pulses) and then transfer mixture to a bowl and stir in the next 9 ingredients (oil - cinnamon) and then add the lamb, kneading with your hands until combined.
Step 3: Using kitchen shears cut around the circumference of each pita and separate into two halves. Place the 4 thicker halves on a counter, interior side up. Divide lamb mixture into 4 equal portions and place one portion in center of each pita half. Using a spatula, spread lamb mixture into an even layer, leaving1/2 border around the edge. Top each lamb portion with 1 thinner pita half. Press each sandwich firmly until lamb mixture spreads to 1/4 inch from edge of pita. Transfer sandwiches to a plate and cover with plastic wrap (***sandwiches can be left at room temp for up to one hour before grilling).
Step 4: Preheat gas grill by turning all burners to high, cover and heat until hot (will take up to 15 minutes) and then turn all burners to medium high.
Step 5: Clean and oil cooking grate and place sandwiches on grill, cover and cook for 5-10 minutes or until bottoms are evenly browned; flip sandwiches and continue to cook until second side are browned -- another 5-10 minutes. Transfer sandwiches to a cutting board and cut each half crosswise and place on platter, passing the sauce separately.
