Storage: This pizza freezes well. Allow to cool completely before wrapping tightly for freezing.
Variation: For a different texture, put the broccoli and sausage on the lower layer, and the tomatoes and mushrooms on the top layer. This way the broccoli stays moist.
Vegetarian Option: Replace the sausage with 4 c sliced onions, lightly browned in 2 T oil. Or, you can keep the sausage and add the onions anyway.
