Preheat oven to 425°F. Combine drained tomatoes, beans, 1/16 teaspoon garlic powder and 1/16 pepper in small bowl; set aside.
Place two 18x12-inch pieces of heavy foil on counter. Place half of bean mixture in center on each piece of foil.
Sprinkle remaining 1/16 teaspoon garlic powder, remaining 1/16 teaspoon pepper and salt over FROZEN fillets. Place 1 fillet on bean mixture for each packet. Double fold top and ends of each piece of foil, leaving space for steam to gather.
Place packets on baking sheet; bake 25 minutes or until fish flakes easily with fork (145°F). Carefully open ends of packets to allow steam to escape before fully opening.
