Start by cleaning the Large Portobello Mushroom (2). To do this, first gently pull out the stem by twisting and pulling on it.
Then, scrape out the gills with a spoon. Then, wash the mushrooms clean and pat them dry with some paper towels.
In the meantime, fire up the grill. Generously drizzle some Olive Oil (to taste) over both sides of the mushrooms and rub it around with your fingers.
Season the mushroom well on both sides with Salt and Pepper (to taste) and Garlic Powder (to taste).
Once your grill is heated and you're ready to go, cook the mushrooms bowl side (cavity side) down for 7 to 8 minutes.
Then take the mushrooms off the grill and prepare the pizza part of this recipe. Smother some Pizza Sauce (to taste) into the mushroom cavity.
Top with some fresh chopped Fresh Basil (to taste) and fill it with Mozzarella Cheese (to taste).
Next, sprinkle over some Italian Seasoning (to taste) and Crushed Red Pepper Flakes (to taste).
Add some Chicken Sausage (to taste) and Red Bell Pepper (to taste).
Then place the mushrooms back on the grill, filling side up, and cook the mushroom for another 8 to 10 minutes (with the lid closed) until the cheese is bubbly and melted.
Serve the pizzas hot with some more fresh chopped basil as garnish.
