zucchini with prosciutto and fontina cheese

My sister, Kortney, told me about this simple, but tasty appetizer.

zucchini (2-3)
prosciutto (package)
fontina cheese

Slice each zucchini in half lengthwise, then slice each half again lengthwise, so you have slices about 1/4" thick. Place on cookie sheet lined with parchment paper. Top each zucchini with a slice of fontina cheese and top that with a thin piece of prosciutto. Drizzle olive oil over them and top with cracked black pepper. Broil in oven just until the cheese melts and the prosciutto begins to brown and crisp. Serve.
