COOK IT.
In a large bowl, mix the water and yeast together. Let sit for 10 minutes, or until the yeast smells fragrant and is foamy.
Stir in the olive oil and salt, then mix in the flour. Knead the dough together until a rough ball of dough forms, then knead the dough for 7-10 minutes, or until the dough is smooth and elastic.
Place the dough ball in a large bowl, cover with a loose dish towel and let rise in a warm place for 2 hours.
When the dough has finished rising, remove it from the bowl, cut the dough in half and save for later
Roll the other half into a round. Place the round onto a pizza pan and begin to build your pizza.
Top with pizza sauce, then sprinkle with garlic powder, salt, and pepper. Top with cheese, peppers, onion, mushroom, olives, pepperoni and sausage.
Preheat your grill or smoker to 400°F. If using a pizza stone, preheat the stone at the same time.
Once grill is preheated, grill the pizza for 7-10 minutes (either on the preheated pizza stone or directly on the grill grates) until the sausage is fully cooked and the crust is golden and crispy.
Remove from the grill, slice, and serve.
