Preheat oven to 350°F and open flame grill to medium high. For spice blend, combine all ingredients in a small mixing bowl and stir well. Set aside. For meatballs, combine all ingredients and 2 tablespoons reserved Moroccan spice blend in a large mixing bowl and combine using your hands until incorporated. Chill mixture for 30 minutes and portion using #20 scoop onto parchment-lined half sheet pan. Once portioned, roll each between hands to form round ball shape. Bake uncovered for 20 - 25 minutes or until internal temperature reaches 165°F. For harissa glaze, in small saucepan over medium-low heat, combine all glaze ingredients and let simmer until glaze consistency, about 5 minutes. Strain glaze to remove garlic pieces. Divide glaze in half, toss meatballs with half and reserve remaining for basting. Skewer 3 meatballs on each skewer. Grill each meatball skewer for 1 to 2 minutes per side, just until grill marked and baste with remaining glaze. Serve alongside prepared Sweet Things® Sweet Potato Puffs (#L0094).
