Combine 1/3 of Char-grilled Capsicums with some of the extra virgin olive oil. Blanch all the tomatoes, peel them and cut them into small pieces. Place fresh tuna slices in a slightly greased baking-tin, spread them with breadcrumbs, basil and chopped capers. Add olives and diced tomatoes, and season everything with salt and pepper. Sprinkle with the remaining olive oil and bake at a temperature of 160? for 15 minutes. Before serving add the warmed up capsicum sauce and garnish everything with basil leaves and Char-grilled capsicum fillets.
