Preheat the grill or grill pan - Preheat the grill or grill pan to medium-high heat.
Roll out the pizza dough - Roll out the pizza dough on a floured surface into a 12-inch circle and transfer to a lightly oiled baking sheet or pizza stone. - If you don't want to make your own pizza dough, store-bought pizza dough can be used instead. You can also use a pre-made crust if preferred.
Grill the peaches - Brush the peach slices with olive oil and grill for 2-3 minutes on each side, until grill marks appear. - Make sure the peaches are ripe but firm, so they don't fall apart on the grill. You can also use a grill pan if you don't have an outdoor grill.
Assemble the pizza - Brush the pizza dough with olive oil and sprinkle with salt. Add the shredded mozzarella cheese, grilled peaches, and torn prosciutto on top. - Be sure to leave a little bit of space around the edges of the dough for the crust. You can also add arugula or fresh basil on top for an extra pop of green.
Bake the pizza - Bake the pizza at 450°F for 10-12 minutes, or until the cheese is melted and bubbly. - Be sure to keep an eye on the pizza while it's in the oven, as it can quickly go from golden brown to burnt.
Drizzle with balsamic glaze - Drizzle the balsamic glaze on top of the pizza. Slice and serve hot. - If you don't have balsamic glaze, you can make your own by reducing balsamic vinegar with a bit of sugar until it reaches a syrupy consistency.
