Caramelized Onions & Mushroom Matzo Pizza

This is my World Famous in My House Matzo Pizza. I caramelized some onions that became part of the base for the sauce for the pizza. The sauce was a fire roasted tomato and garlic sauce. You don't get thin crust pizza kosher for Passover any better than this. The onions were layered on top of the sauce, under the cheese. Baby bellas were broken up and placed on top. The plain cheese was for Brice. Later this week I might do some basil and tomato pizza's or spinach, mushroom and feta.
