About 10-15 minutes before you're ready to begin prepping the pizzas, heat all the burners on your grill to high heat. When you are ready to place the dough on the grill, turn half of the burners off, so you have some cooler and hotter spots. Place the dough onto the grill carefully (you may need to use two hands to do this, since the dough can be fragile. Be careful not to burn yourself!). Cook the dough for about 2-3 minutes, or until char marks start to form on the dough.
Take the pizza off the grill and then begin assembling the pizzas. On the charred side of the dough, spread the skinny pesto ranch until almost to the edge of the pizza. Then top with desired amount of cheese, chicken, bacon, tomatoes, and green onions.
Once pizzas are assembled, place them back on the grill, closing the grill to keep the heat in. Pizzas are finished when the dough is cooked through and the cheese is melted. You may need to watch the pizzas carefully and move them to a cooler spot if they are beginning to char too quickly.
Take pizzas off the grill, drizzle with additional pesto ranch, cut, and enjoy!
