Lay out slices of bread and butter one side of each.
On the unbuttered side, layer fresh mozzarella, strawberries, basil leaves and prosciutto. Drizzle with balsamic glaze; place remaining bread on top and transfer to a preheated nonstick pan. Cook for approximately one minute, pressing down with a spatula. Flip and repeat until the bread is golden brown.
Remove, drizzle with extra balsamic glaze over top if desired, cut and serve.
