Prepare the dough by dissolving yeast in warm water with sugar.
Mix flour and salt in a large bowl, then add the yeast mixture and olive oil.
Knead the dough on a floured surface for about 8-10 minutes until smooth.
Let the dough rise in a warm place covered with a towel for about 1 hour.
Preheat your oven to 475°F (245°C).
Roll out the dough into a triangle shape on parchment paper.
Spread mozzarella cheese evenly over the dough, leaving edges clear.
Add the desired toppings to resemble ornaments on a tree.
Sprinkle Parmesan cheese on top for added flavor.
Bake in the preheated oven for 12-15 minutes, or until golden brown.
Let it cool slightly, then garnish with fresh basil leaves if desired.
