In a large mixing bowl, combine the flour, salt, and sugar.

In a small bowl, dissolve the yeast in warm water and let it sit for 5 minutes, or until foamy.

Add the yeast mixture and olive oil to the flour mixture. Stir until a soft dough forms.

Knead the dough on a lightly floured surface for 5 minutes, or until smooth and elastic.

Place the dough in a greased bowl and cover with a clean kitchen towel. Let it rise for 30 minutes, or until doubled in size.

Preheat the oven to 450°F (230°C).

Punch down the dough and divide it into 4 equal pieces.

On a lightly floured surface, roll out each piece into a heart shape using the heart-shaped cookie cutter as a guide.

Place the heart-shaped pizza crusts on a greased baking sheet.

Spread pizza sauce evenly over each crust, leaving a small border around the edges.

Sprinkle shredded mozzarella cheese over the sauce.

Bake the pizzas in the preheated oven for 12-15 minutes, or until the cheese is melted and bubbly.

Remove from the oven and let the pizzas cool for a few minutes before serving. Enjoy!

Fold a pepperoni slice in half and use a pair of kitchen shears to trim the edges into the shape of half of a heart. Arrange a layer of pepperoni hearts over the pizza dough.
