Preheat your oven to 425 degrees. Allow your pizza dough to come to room temperature if frozen or refrigerated. On a lightly floured surface, stretch the dough into a 16 inch round. Spray a perforated pizza pan with non-stick spray and sprinkle it lightly with corn meal (if desired). Transfer the stretched dough onto the pizza pan.
Spread the pizza sauce evenly over the dough, leaving a one inch area of crust around the outside edge. Top with cheese, pineapple, diced ham slices and thinly sliced jalapeno.
Bake in the fully preheated oven (425 degrees) for 15-20 minutes or until the crust is golden brown and the cheese is melted and bubbly. Enjoy!
