Preheat your oven to 400°F and place a baking sheet in the oven to heat up.
Lay the tortilla on a clean, flat surface, and spread the ranch dressing evenly over the tortilla, leaving a small border around the edges for the crust.
Sprinkle the mozzarella cheese over the ranch dressing as the first layer of your pizza, then the diced grilled chicken and bacon bits evenly on top.
Carefully remove the hot baking sheet from the oven (use oven mitts) and place the prepared tortilla pizza on it.
Slide the baking sheet with the pizza into the preheated oven and bake for about 8 minutes, or until the edges of the tortilla are crisp, and the cheese is melted and bubbly.
Carefully remove the Chicken Bacon Ranch Tortilla Pizza from the oven (using oven mitts) and let it cool for a minute.
Sprinkle the chopped parsley over the pizza to add a fresh touch.
Using a pizza cutter or a sharp knife, slice the tortilla pizza into wedges or squares, and serve it hot. Enjoy!
