Preheat your oven to 475°F (245°C).
Roll out your pre-made pizza crust on a floured surface to your desired thickness, then transfer it to a baking sheet or pizza stone.
Evenly spread the pizza sauce over the crust, leaving a small border around the edges.
Sprinkle the shredded mozzarella cheese generously over the sauce.
Distribute the pineapple chunks and sliced ham (if using) evenly over the cheese.
Lightly drizzle olive oil over the toppings, and sprinkle with Italian seasoning if desired.
Bake in the preheated oven for 12-15 minutes, or until the cheese is bubbly and the crust is golden brown. Slice and enjoy!
