Preheat your oven to 350 degrees F.
Unwrap the dinner rolls and use a bread knife to cut the rolls in half so all the tops are separated from the bottoms. Set the tops aside.
Place the bottoms of the rolls on a baking sheet. I like to line my baking sheet with a Silicon Baking Matbecause it makes clean up so quick and easy.
Spread the pizza sauce over the bottom half of the rolls, going all the way to the edges. Sprinkle the sauce with Italian seasoning.
Layer the ham slices over the pizza sauce. Depending on the size of your ham slices it could take more or less ham to cover all the rolls and get a good layer of meat. Use your best judgement on this.
Top the ham with slices of mozzarella cheese. (I got mine from the deli counter.)
Sprinkle the pineapple all over the cheese, being sure to spread it out for even coverage. You want some pineapple in every bite.
Place the roll tops over the pineapple, cut side towards the fruit.
Use a pastry brush to brush the tops of the rolls with melted butter. Sprinkle salt & pepper over the butter.
Bake for 15 minutes, or until the edges of the rolls are crusty and the cheese is melted.
Carefully remove from the oven. Cut the sliders apart with a sharp knife once they are cool enough to handle. Transfer to a serving plate and serve immediately.
