Make mushroom pan sausage: Process mushrooms and garlic in food processor until finely chopped. Heat ghee and olive oil in medium sauté pan over medium heat. Add processed mushrooms and garlic, Chorizo Spice Blend, salt, and pepper. Cook, stirring occasionally until mushrooms have released water and are browned (about 8-10 min). Remove from heat and set aside.
Make pizzas: While pan Sauage is cooking, toast corn tortillas in a toaster oven or in a dry cast iron skillet until just starting to crisp; they will finish crisping in oven. Set aside.
Preheat oven to 425℉. Place tortillas on a baking rack set over a baking tray. Sprinkle tortillas with cheese and Swiss chard (or spinach). Then, using small spoons, drop mushroom pan sausage on top. Sprinkle chopped tomatoes with salt, pepper, and garlic powder, and add to pizzas. Then top with black beans, diced bell peppers, diced jalapeños, and diced red onions. Sprinkle each pizza with pumpkins seeds. Bake about 6-9 minutes until cheese is melting and topping are warm. While pizzas are baking, prep sauce, avocado, and cilantro.
After removing from the oven, top with diced avocado (sprinkled with salt, pepper, and garlic powder), drizzle with Sriracha Yogurt Sauce, and garnish with cilantro flowers, leaves, or microgreens. Serve immediately.
