Serving simple broiled tilapia with spicy Spanish brava sauce is a delicious and healthy way to get more fish into your diet. Start the sauce by sautéing onions in olive oil, then adding paprika, red pepper flakes, garlic, and tomatoes. After about 15 minutes, purée the sauce and add in some sherry vinegar and a few dashes of hot sauce for a little zing. Rub the tilapia with oil, season with salt and pepper, and broil for a few minutes. Top the fish with a little sauce and serve with a Spanish-y salad for a light dinner.
