In a bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until frothy.

In a large mixing bowl, combine flour and salt. Add the yeast mixture and olive oil. Mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth. Let it rise in a warm place for 30 minutes.

Preheat the oven to 475?F (245?C) and place the pizza stone inside.

Roll out the dough on a floured surface to your desired thickness.

Transfer the rolled dough to a pizza peel or baking sheet. Spread pizza sauce evenly over the dough.

Sprinkle mozzarella cheese over the sauce, then add diced ham and pineapple chunks. Optionally, sprinkle oregano on top.

Carefully slide the pizza onto the preheated pizza stone in the oven.

Bake for 12-15 minutes or until the crust is golden and the cheese is bubbly.

Remove from the oven, let cool for a few minutes, then slice and serve.
