Preheat oven to 400 degrees

In a small pot, melt butter and oil together. Saute onion and garlic until soft, 3-4 minutes. Add gluten free flour, and cook for 3 minutes, while whisking. 

Add milk, cheese and spices and cook until thickened. This will take approximately 5 minutes. Remove from heat and set aside. 

Next, prepare the pizza toppings. Chop the chicken in to small chunks and cook in a well oiled, hot skillet. Once cooked, remove to a side dish and cook the bacon. Cook bacon to desired crispness, and remove from heat. 

Next, cook diced bell pepper (I used an orange one.) Cook for about 3 minutes. Remove from skillet, and then cook spinach until completely wilted. Remove from pan. 

Cook Schar crust, brushed with oil but otherwise untopped, in oven to brown. 3 minutes tops. Then remove from oven to add toppings.

Add white sauce to pizza crust, filling the sunken well in the crust, until it reaches the edge. Then add cooked chicken, bacon, bell pepper, and then finally cooked spinach. Then top with mozzarella cheese. Place topped pizza in the oven and bake for 10-12 minutes, until the cheese is melted and just barely browned. 

Remove from oven and allow to cool approximately 5 minutes before cutting and serving. Enjoy!
