Evenly butter bread on both sides of each slice. In a nonstick skillet over medium heat, cook buttered bread until it is golden brown, flipping frequently to evenly brown both sides. Place bread on serving plate.
Top each slice of bread evenly with Toma, followed by peach slices. Sprinkle toasted pistachios over the top. Drizzle toasts with honey and finish with a generous pinch of flakey sea salt.
