Make the dough: In a small bowl, combine warm water, sugar, and yeast. Let sit for 5–10 minutes until foamy. In a large mixing bowl, combine flour and salt. Add the yeast mixture and olive oil, and mix until dough forms. Knead on a floured surface for 5–7 minutes until smooth and elastic. Place in a lightly oiled bowl, cover, and let rise for 1 hour or until doubled in size.

Preheat the oven: If using a pizza stone, place it in the oven and preheat to 475°F (245°C) for at least 30 minutes. If using a baking sheet, lightly grease it and preheat the oven to the same temperature.

Shape the dough: Punch down the risen dough and turn it onto a floured surface. Roll or stretch into a 12-inch circle for a traditional pizza or shape it to fit your baking sheet or pizza pan. Transfer to a sheet of parchment paper if using a stone.

Assemble the pizza: Spread pizza sauce evenly over the dough, leaving a small border around the edge. Sprinkle with shredded mozzarella, then evenly distribute the ham and pineapple chunks over the top. Sprinkle with oregano or Italian seasoning.

Bake: Transfer the pizza to the oven — either directly onto the preheated stone or with the baking sheet. Bake for 12–15 minutes, or until the crust is golden and the cheese is melted and bubbly.

Finish and serve: Remove from the oven, brush the crust edges with olive oil for extra shine and flavor, and let cool for 5 minutes before slicing. Serve hot, and add red pepper flakes or extra herbs if desired.
