Preheat the oven to 450 degrees F.
On a lightly floured surface, roll out the dough balls to form 2 long rectangles and put them onto parchment lined baking sheets.
Put the olive oil in a medium skillet over medium-high heat and add the red pepper flakes. Allow the flakes to sizzle and season the oil. Add the prosciutto and onion and cook until browned, about 7 to 10 minutes. Stir in the pineapple. Divide the mixture and spread it over the 2 pizza doughs. Top each pizza with half the mozzarella cheese and a few grindings of black pepper. Cook until the cheese is melted, about 7 to10 minutes. Sprinkle with fresh chopped basil for a flavor boost. Slice each pizza on the bias with a pizza cutter and serve.
