Directions

1. Preheat oven to 475 degrees F and lightly flour a baking sheet or pizza pan.
2. Heat 2 tbsp olive oil in a medium nonstick pan over medium-low heat. Add the onions and allow to caramelize for about 15 minutes, stirring occasionally. 
3. Once onions have caramelized, drizzle the balsamic vinegar over them, stir to absorb, and cook for 1 more minute. Remove from heat and set aside.
4. On a lightly-floured surface, roll dough out into a 10" circle and transfer to the prepared baking sheet.
5. Use a pastry brush (or clean hands) to generously cover dough with olive oil. Scatter the feta evenly atop the oiled dough.
6. Arrange the peach slices and onions on top of the feta. Season liberally with salt and pepper.
7. Bake for 12-15 minutes, or until dough is golden-brown and peach slices and feta have a bit of color.
8. Top with the freshly-torn basil, cut into wedges and serve.
