In a large mixing bowl, stir together wine, thyme, vinegar, 2 tablespoons of the olive oil, paprika and salt. Cut fish into 1/2-inch thick medallions, place in a bowl and stir gently but thoroughly and allow to marinate 1 hour. Remove fish from marinade and pat dry. Dust with flour and season with salt and pepper. Reserve marinade for later. Heat remaining oil in a 12-inch saute pan over medium-high heat until just smoking. Add tuna pieces 4 to 5 at a time and cook in batches until golden brown on both sides and remove to a plate. Add cumin, saffron, onion, garlic and bell pepper to the pan and cook until softened, about 10 to 12 minutes. Add tomato, sherry and reserved marinade and bring to a boil. Add cooked tuna pieces, simmer 10 minutes and serve. This recipe yields 4 main course servings.
