Preheat oven to 400 °. In a blender or food processor, add basil, garlic, EVOO, salt and pepper and oil. Pulse until well blended. Add more EVOO, if needed to make a smooth, spreadable consistency. Arrange thickly sliced bread on baking sheet and spread about 1/2 basil mixture onto bread. Sprinkle mozzarella over mixture. Add a slice of Provolone cheese to each slice of bread. Slice tomatoes and arrange overlapping on bread. Sprinkle with salt and pepper. Bake about 7 minutes. Drizzle with remaining basil mixture and place under the broiler until bubbly and browned, about 5 minutes, but be sure and watch so as not to burn. Sprinkle crushed red pepper flakes on top, if desired. I use a multigrain or whole wheat bread, if I can find it.
