Chop the baby spinach and set aside, also cut your chicken into small chunks
Sauce
Begin by heating a frying pan at medium-low heat. Add the Olive Oil and crushed garlic.
Cook the garlic until just browned, then add the chopped spinach and stir until spinach is cooked thoroughly.
Next, add bone broth and heavy cream and stir until combined.
When the broth and cream begin to steam, add the Parmesan Cheese, Italian Seasoning, Garlic salt, and Rice flour. Stir until combined and sauce thickens.
Crust
Place a sheet of parchment paper on the pizza pan, and place one of the gluten free pizza crusts on the parchment paper.
Add the sauce to the crust and spread around evenly.
Add chicken, then top with mozzarella cheese.
Place in the oven and bake for 8-10 minutes until the cheese begins to brown. Since the crust is thin and flat, the cheese and sauce will tend to run over the edge (hence the parchment paper for easy cleanup) but you can usually use a butter knife to scoop the overflow back on top of the pizza.
