Mix the broccoli rice, egg, mozzarella, and parmesan in a bowl. Add salt and pepper to taste.
Line some parchment into a baking sheet and transfer the mixture. Press it to make it at least ¼-⅛ inch thick.
Put in the pre-heated oven for 20 minutes. When the crusts look dry and the edges turn brown, remove from the oven and top with chicken, mozzarella, and Alfredo sauce.
Bake again for 10 to 15 minutes or until the cheese is golden in color. Add bacon and grated parmesan if preferred. Cut and serve while hot.

Notes
Cauliflower rice is also good for the pizza crust.
