Dice prosciutto and place in a medium non-stick pan over medium-high heat. Sauté until crispy and set aside.
Heat butter in a large sauté pan over medium-high heat. Add the squash ribbons and sauté for 2-3 minutes. Add cracked black pepper. Remove pan from heat and add grated BelGioioso American Grana®. Toss to combine.
Place ribbons decoratively on a platter and top with crisp prosciutto. Serve immediately.
*Prepared by using a peeler to make thin ribbons using the whole length of the squash (peel all four sides to get the most color.) Stop peeling when you get to the seeds.
