Use your favorite seasoning blend for the grilled fish, then serve on hoagie buns to make these quick dinner sandwiches.
Thaw fish, if frozen. Rinse fish; pat dry with paper towels. Brush fish with lemon juice. Sprinkle desired seasoning evenly over all sides of fish.
Place fish in a greased grill basket, tucking under any thin edges. (Or, grill fish on the greased rack of the grill.) For a charcoal grill, place grill basket on the rack of an uncovered grill directly over medium coals and grill until fish flakes easily when tested with a fork (allow 4 to 6 minutes per 1/2-inch thickness of fish), turning basket once halfway through grilling. (For a gas grill, preheat grill on high for 10 to 15 minutes. Reduce heat to medium. Place grill basket on grill rack over heat. Cover and grill as above.)
Remove fish from grill basket. Serve fillets on buns. Makes 4 servings.
