About a half hour before you're ready to eat, take your friselle, dip them briefly in tepid water and place them on individual plates. Pour some olive oil over each frisella.
Now prepare a tomato salad with the tomatoes, olive oil, oregano, salt and pepper, and spoon some of the salad onto each plate, covering the top of the frisella.
Now you can add whatever other toppings strike your fancy. Let rest until you're ready to eat.
Just before serving, drizzle a bit more olive oil over each plate.
