Preheat oven to 400 degrees F.
Arrange the pitas on baking sheets or sheets. In a bowl combine the hummus and the olive tapanade. Spread the hummus on pitas and top with cheese, like pizza. Combine the chopped anchovies, peppers, artichokes, and pepperoncini. Cover the pizzas with the chopped mixture. Bake 10 to 12 minutes to melt cheese and crisp the pitas. Cut pizzas into wedges and garnish with parsley.
