Preheat oven to 400 degrees Fahrenheit.
On a lightly floured surface, unfold puff pastry and dust with flour on top. Use a rolling pin to gently roll pastry so it is a bit thinner.
Line a 9 x 13 sheet pan with parchment paper and place puff pastry onto pan.
Score a half inch border around the pastry and dock holes all over the middle. Pre bake for 10 minutes until lightly golden brown.
Let it cool for 15 minutes.
Prepare the tomatoes by sprinkling salt on them and letting them sit for 15-20 minutes.
Layer tomatoes, peaches, and mozzarella on pastry. Drizzle with olive oil, sprinkle with salt, and bake for 25-28 minutes.
Make the basil oil by blending olive oil and basil leaves together.
Garnish the tart with basil oil, balsamic, and fresh basil leaves.
