Tomato and Mozzarella Triangles These are great for a little snack or picnic in the park. You could also add chopped olives, anchovies or capers to the filling. Place them in the oven and bake for 15 minutes or until they are golden brown. Eat the triangles warm or cold. This recipe comes from my book Sophie Conran's Pies published by Collins.
