(Vermont mozzarella, roasted peppers, dry-cured sausage, and mushroom pizza.)
They were pre-baked before they were topped.
Then they were diced along with the sausage. I did not photograph the mushrooms that I sauteed, but trust me, they were in there.
The verdict? I likened this to the worst pizza crust that I ever made with wheat flour, but it is the best of the non-wheat pizza mixes I have tried. The crust was tough and tasteless, which was surprising considering all the herbs in it. It is hard to eat using a fork. On the plus side, it supports the ingredients well if you eat pizza with your hands (I don't).
(The frozen crust, when re-heated with toppings a week later was not as hard as the one eaten directly after baking.)
