1/4 teaspoon garlic powder

Cut pork into 1 inch pieces (should have about 32). Place in medium bowl. Combine spices. Reserve 2 tablespoons. Sprinkle the rest over the pork and stir to coat. Let stand 15 minutes. Mix together remaining ingredients. Heat grill. Spray grill basket with cooking spray and spoon pork into basket. Cook on covered grill 10-12 minutes over medium heat, shaking basket or stirring once or twice, till pork is no longer pink in center. Serve on skewers or with toothpicks for dipping into sauce.
