Prepare the Dough:
In a large mixing bowl, combine the flour, salt, sugar, and yeast.
Gradually add the warm water and olive oil while mixing until a dough forms.
Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.
Place the dough in a lightly oiled bowl, cover with a clean towel, and let it rise in a warm place for 1-2 hours until doubled in size.
Shape the Dough:
Preheat your oven to 475°F (245°C) and line a baking sheet with parchment paper.
Roll out the dough into a large circle and shape it into a heart using a knife or by pinching the edges.
Transfer the heart-shaped dough onto the prepared baking sheet.
Add the Toppings:
Spread the pizza sauce evenly over the dough, leaving a small border around the edges.
Sprinkle shredded mozzarella cheese over the sauce.
Add crumbled cooked sausage and sliced mushrooms as desired.
Bake the Pizza:
Bake the pizza in the preheated oven for 12-15 minutes, or until the crust is golden and the cheese is bubbly and slightly browned.
Remove from the oven and let it cool slightly before garnishing with fresh parsley.

Decoration Tips:

Use heart-shaped cookie cutters to pre-shape sausage pieces for a cohesive theme.
Drizzle a bit of olive oil over the crust before baking for a golden, glossy finish.
Serve the pizza on a white platter to emphasize its heart shape and vibrant toppings.
Happy Baking!
