GRILL DIRECTIONS: Heat grill. Crumble muffins into small bowl. Add pecans and margarine; mix well.
Sprinkle cavities of fish with salt and pepper. Fill with stuffing; secure fish with string or toothpicks. Brush both sides of fish generously with oil; place on sheet of heavy-duty foil.
When ready to grill, place foil on gas grill over medium heat or on charcoal grill 6 to 8 inches from medium coals; cover grill. Cook 10 to 15 minutes or until fish flakes easily with fork, turning fish several times.
