In a saucepan, bring broth to a boil. Add the rice, chili powder and garlic; return to a boil. Reduce heat; cover and simmer for 15-20 minutes or until rice is tender. Add the tomatoes, peppers and onion. Cover and cook over medium heat until vegetables are tender. Add fish, shrimp and orange juice concentrate. Cover and simmer for 2-4 minutes or until the fish flakes easily with a fork and the shrimp turn pink. Yield: 6 servings.
