Directions: Prepare grill to medium-high heat. Squeeze orange to extract 1/4 cup juice. Combine orange juice, basil leaves, olive oil, and garlic cloves in a mini chopper; add 1/4 teaspoon salt. Process basil leaf mixture until finely chopped. Sprinkle 1/4 teaspoon salt and 1/8 teaspoon freshly ground black pepper evenly over fish; thread fish onto 4 (12-inch) skewers. Grill fish 10 minutes or until fish flakes easily when tested with a fork or until desired degree of doneness, turning occasionally. Drizzle fish with sauce, or serve sauce separately. Garnish sauce with orange rind, if desired.
