Bring 2 quarts water to boil.
Cut tuna into 3/4-inch cubes and drop into boiling water. Lower heat to simmer and cook 2 minutes. Drain carefully and set onto serving platter to cool in one layer. In a mixing bowl, stir together olive oil, vinegar, garlic, tomatoes, mint, crushed peppers and oregano flowers. When tuna is cool, pour liquid over and set aside. In a 6-inch to 8-inch non-stick saute pan, heat 3 tablespoons oil until smoking. In a mixing bowl, stir together eggs, scallions and Pecorino. Pour into smoking pan and cook until omelet is set. Cool and cut into 6 pieces. Divide tuna over pieces of frocia and serve.
