Preheat the oven to 500°F (if using a baking sheet) or as high as it will go (if using a baking stone/steel; place the stone/steel in the bottom third of the oven before you start preheating).
Cook the chopped bacon in a medium skillet over medium heat until it just begins to crisp up at the edges, about 5 minutes. Remove the skillet from the heat and transfer the bacon to a paper towel–lined plate to drain. Do not wipe out the skillet.
If you're using a baking stone/steel, turn the oven to Broil on high.
Stretch or roll out your dough to a 12-inch circle, then transfer it to an oiled or parchment-lined baking sheet or a lightly floured pizza peel (if using a baking stone/steel).
Use a pastry brush to coat the dough lightly with bacon grease from the skillet. Spread the sauce evenly over the dough, leaving a ½-inch border all around. Top with half of the cheese, then the ham, pineapple, and bacon, spreading everything out evenly. Finish with the remaining cheese.
Transfer the pizza to the oven and bake until the crust is golden and the cheese has browned in spots—8 to 10 minutes on the baking sheet, 6 to 8 minutes on the baking stone/steel.
Remove the pizza from the oven. Let it cool for about 5 minutes before slicing and serving.
