Pull the pizza dough out of the refrigerator at least two hours to come up to room temperature before you are ready to bake.

Place pizza stone on the center oven rack of a cold oven. Preheat oven to 500°F for one hour.

Separate the fresh mozzarella slices, and use a heart-shaped cutter to create individual hearts. Cover and store in the refrigerator until ready to use.

Cut each pepperoni slice into heart shapes using a heart-shaped cutter. Set aside.

Sprinkle flour on a sheet of parchment paper to prevent the dough from sticking.

Place the dough in the center and spread out into a heart shape with your hands. Pinch the bottom to form a point and gradually spread the dough upward and outward.

Once shaped, spread the pizza sauce over the crust, leaving a clean edge around the sides.

Sprinkle the grated mozzarella over the sauce, then sprinkle on the Parmesan cheese.

Spread the pepperoni hearts over the cheese, then add the mozzarella hearts.

Sprinkle the sliced sweet peppers and red onions over the top, and add Italian seasoning.

Slide the pizza onto a pizza peel and carefully transfer to the hot baking stone. Bake for 10 minutes until the crust is golden brown and cheese is bubbly.

Remove the pizza from the oven and allow to cool slightly before serving.
