Bring a medium sauté to medium high heat with the olive oil. Add the sliced leeks and sauté for 6-8 minutes until soft. Season with salt and pepper and set aside.
Pre-heat your oven to 500 degrees. Thirty minutes before cooking the pizza, put your pizza stone in the oven.
Divide the pizza dough into 2 even pieces. Stretch each piece of dough in a circular motion, then lay them both out on a flat surface and flatten out using a rolling pin. If you have a pizza peel, sprinkle some flour on it and place the stretched out dough on the peel.
Once your 2 pizza doughs are flat and ready to be heated, use a spoon to spread the roasted garlic paste all around the dough leaving a little bit for the crust.
Top each pizza with half of the shredded cheese, fresh mozzarella, sautéed leeks and sliced brussels sprouts. Transfer the pizzas into the oven and bake for 12-13 minutes until the crust is perfect.
Remove pizza from the oven and top with the cooked bacon. Season with salt and pepper and additional red pepper flakes if needed slice and serve.
