Have you seen Portabella mushrooms? They’re about the size of an English muffin. All you have to do to make a Portabella mini pizza is top a cooked mushroom cap with tomato sauce, low fat mozzarella cheese, and the broil!
You will get three times the protein and four times the fiber than when using an English muffin. If desired, you can make it into a veggie pizza with thin onion slices and peppers, but you already have the mushroom!
