Choose peaches that are ripe but still slightly firm so they slice cleanly and hold their shape on the toast. If peaches are out of season, grill them briefly to coax out sweetness or substitute nectarines. For extra crunch, toast the bread in the oven at 425°F on a sheet pan if you’re making a large batch. Burrata or goat cheese can replace mozzarella, and arugula can stand in for basil for a peppery note. Assemble just before serving to keep the toast crisp, and adjust balsamic and salt sparingly since prosciutto is already salty.
