Preheat oven to 400 degrees F (205 degrees C). Sprinkle a round pizza pan with a light layer of Cornmeal (1 tablespoon).
Add Extra-Virgin Olive Oil (1 tablespoon) to large sauté pan along with Sweet Onion (1). Toss to coat and cook over medium-low heat, stirring frequently for 15-20 minutes or until onions become soft and caramelized. Remove from the pan and set aside.
While onions cook, roll the Gluten-Free Pizza Dough (1) out according to package’s directions. Prebake pizza for 10 minutes. Remove and set aside.
In the same skillet as you cooked the onions, add Extra-Virgin Olive Oil (1 tablespoon), followed by Garlic (3 clove). Cook 1-2 minutes, stirring frequently until fragrant.
Add Baby Bella Mushroom (8 ounce) and stir until coated in olive oil and garlic. Add Water (1 tablespoon), followed by Dried Thyme (1/2 teaspoon), Dried Basil (1/2 teaspoon), Sea Salt (1/4 teaspoon), and Freshly Ground Black Pepper (1/8 teaspoon). Stir until seasonings are well mixed, then cook 5-6 minutes, stirring occasionally, until mushrooms are tender and browned.
Add Frozen Shrimp (16), tails removed, to the mushrooms, then stir and cook 2-3 minutes. Remove mushrooms and shrimp from pan, leaving as much of the juice in the pan as possible, then set aside.
In a small bowl, mix Water (1 tablespoon) with Corn Starch (1 teaspoon). Add mixture to hot pan with leftover seasoning and juice, along with Milk, whole or 2% (1/4 cup), Garlic Salt (1/4 teaspoon), and Ground Black Pepper (1/4 teaspoon). Bring to a low boil, then reduce heat and allow to simmer for 3-4 minutes or until thick. This does not make a large amount of sauce, but you just need enough for a light coating over the pizza.
Top prebaked gluten-free pizza dough with sauce, followed by Fresh Baby Spinach (1 handful), Fresh Mozzarella Cheese Ball (4 ounce), caramelized onions, mushrooms, and shrimp. Finally, add Shaved Parmesan Cheese (1.5 ounce).
Bake additional 5-6 minutes, or until cheese is melted and pizza is warmed through.
Garnish with Fresh Parsley (to taste), additional shaved parmesan, and Crushed Red Pepper Flakes (to taste) if desired. Serve immediately and enjoy!
