Seed and dice the tomatoes. In a hot frying pan, heat 1/2 Tbls. of the butter. Add the diced tomatoes, capers, Worchestershire sauce, lemon juice, salt and pepper. Cook on low heat quickly for about 2 minutes. Remove from heat and stir in remaining 2 Tbls. of butter and set aside. DO NOT REHEAT. Salt and pepper the fillets. Heat a frying pan; then add the oil. When oil is hot, add the fillets and brown on both sides, turning only once. This will take about 3 minutes per side. Remove to a plate and spoon the tomato sauce over the fillets.
