If you're mad about mushrooms, especially on your pizza, this is for you! You'll get rich Portobello flavor in every bite, because the mushroom itself is your pizza. Stuffed with savory pizza toppings like cheese and pepperoni, these make terrific appetizers, or served with a salad, a meal in themselves. The mushrooms are baked and then set on toasted slices of crusty French bread for stability and crunch. Courtesy of Mr.Food.
