Dredge fillets in flour to lightly dust. Place in sauté pan with a small amount of hot butter over medium heat. Cook the first side, being careful not to burn.
Turn over fish when golden, and reduce heat while adding garlic, tomatoes, capers, white wine, and lemon juice. Cover to hold steam in and cook until fish is fork tender.
Add basil and serve immediately. Garnish with a sprig of parsley or kale and a lemon wedge.
