When I saw this recipe in a recent issue of Martha Stewart Living, I knew within two seconds of reading the title that I would be making it. I love crostini and I love avocado. The fact that it also involves crispy prosciutto and manchego cheese is just a plus. To make this delectable appetizer, you don't really need any cooking skills; you basically toast baguette slices, crisp the prosciutto, and layer it with mashed avocado and shaved cheese. Seriously, these crostini are incredibly easy, and the resulting bite is sure to be a hit with guests. It's also totally versatile: it would be equally delicious to start a Mexican, Spanish, or Italian menu. Learn the uncomplicated preparation after the jump.
