Place your pizza stone on the middle rack of your oven. If you do not have a pizza stone, take your largest baking tray and place it in the oven face down.
Preheat oven to 500°F. Let the stone or tray preheat for at least 30 minutes before baking your pizza.
Core the peach and the apricot, then slice them into thin wedges.
Stretch the dough into a 12-inch circle and lay it onto a lightly floured pizza peel or parchment paper.
To stretch the dough, use your fingers to press the dough outward; this creates the crust. Once the pizza is the size of your hands, you can drape the dough over both sets of knuckles, make a fist, and then pull and rotate to stretch the dough to your desired size.
Spread the olive oil over the pizza, leaving 1 inch around the perimeter for the crust.
Top the pizza with the grated Parmigiano Reggiano, goat cheese, peach jam, onions, fresh sliced peaches, and apricots.
Use a pizza peel or parchment paper to transfer the pizza to the preheated pizza stone or tray.
Bake for 15-20 minutes or until the pizza is a deep golden brown.
