Preheat your oven to 425°F (220°C).
In a medium skillet over medium heat, cook the sliced Johnsonville sausage for 5 minutes until browned and heated through. Remove from heat.
Place the pre-baked pizza crust on a large oven-safe skillet or baking sheet.
Spread the pizza sauce evenly over the crust, leaving a small border around the edges.
Sprinkle half of the shredded mozzarella cheese over the sauce.
Distribute the cooked sausage slices and pepperoni evenly on top of the cheese layer.
Add the remaining mozzarella cheese over the toppings for extra cheesiness.
Bake the pizza in the preheated oven for 12 to 15 minutes, or until the cheese is melted, bubbly, and lightly golden.
Remove from the oven and let cool for 3 minutes before slicing and serving.
