Add the canned tomatoes, 1/4 tsp black pepper and 1/2 tsp salt to the pan. Bring to a boil.
Boil for 3-5 minutes or until slightly thick. Remove from heat and puree. Stir in garam masala, paprika and yogurt. Set aside.
In a large bowl, mix the ground chicken, cumin, cayenne, ginger, cinnamon, lemon juice and salt. Press chicken mix into an eight-inch pizza pan. Cover with plastic wrap and press again or use a rolling pin to make the chicken as flat and even as possible. Remove the plastic wrap.
Bake chicken crust in a 400 degree F oven for 20 minutes, chicken crust will begin to brown.
Remove from oven and spread pizza sauce over the chicken crust, leaving a 1/4-inch gap around the edges.
Distribute the spinach on top of the sauce.
Return the pizza to oven for another 5 minutes. Remove and sprinkle with nutritional yeast, serve while hot!
Recipe Notes
Let the ground chicken mix sit in the refrigerator overnight to really incorporate all of the flavors.
