Preheat your oven to 475°F (245°C).
Roll out the pizza dough on a floured surface to your desired thickness.
Transfer the dough to a pizza stone or baking sheet.
Spread the pizza sauce evenly over the dough.
Sprinkle the shredded mozzarella cheese over the sauce.
Add the diced ham and pineapple chunks evenly over the cheese.
If using, add the sliced red onion and bell pepper.
Drizzle the olive oil over the top.
Bake in the preheated oven for 12-15 minutes, or until the crust is golden and the cheese is bubbly.
Remove from the oven, let cool slightly, slice, and serve.
