Preheat the oven to 450°F and place a baking sheet inside to heat.
Roll the pizza dough into a 12-inch circle on parchment paper.
Spread the Alfredo sauce evenly over the dough to form the first layer.
Sprinkle half the mozzarella cheese over the Alfredo sauce.
Spoon the marinara sauce over the mozzarella in an even layer.
Add the pepperoni and sausage crumbles on top of the marinara.
Scatter the remaining mozzarella cheese, then cover with the cheddar cheese to create the top yellow band.
Finish with the black olives and green bell peppers scattered across the surface.
Transfer the pizza on the parchment to the hot baking sheet and bake for 12 to 15 minutes until the crust is golden and the cheese is fully melted.
Remove from the oven and let it rest for 3 minutes before slicing.
