We've all been there — you need an appetizer that will make a great impression but doesn't require you to slave away in your kitchen. This crostini is sure to deliver on both accounts. The creaminess of the avocado, saltiness of the prosciutto, and nuttiness of the Parmesan combine to create the perfect bite.
Turn on the broiler. Slice the bread into 1-inch thick toasts — cut the larger slices from the middle of the loaf in half to keep all the toasts at a similar size. Arrange the bread on a baking sheet and bake under the broiler until lightly toasted.
Meanwhile, mash the avocado until smooth in a small bowl and season with salt to taste. Once you're ready to start assembling the crostini, rub each of the toasts with garlic and spread the avocado evenly among them. Next, top the crostini with a piece of prosciutto and shaved Parmesan and finish with a light drizzle of extra-virgin olive oil.
