Dip each side of the feta slices in the cornstarch to coat.
Heat a sauté pan over medium-high, then add the avocado oil. Add the feta slices and pan fry them for about 45-75 seconds per side. Remove them and place them onto a napkin.
Add the arugula to a bowl, drizzle with olive oil and a pinch of salt. Massage to coat.
Place a slice of prosciutto onto a flat surface, then to one side add a small amount of arugula, then a slice of the feta on top, then a slice of peach on top of that. Carefully roll the prosciutto while keeping the ingredients in place. After one roll, fold over one edge slightly at an angle and continue to roll it up into a slight "cone" shape, so the peach and feta stick out slightly out of one side. Repeat with remaining ingredients.
Place the rolls onto a plate, then drizzle with hot honey and a sprinkle of pistachios.
