These are so easy, and can be made ahead. To make more, simply multiply the ingredients. Store the phyllo cups airtight to stay crisp. (Otherwise, refresh them in a warm oven). This is a great snack, and a good side or starter with grilled meats! Top with mozzarella or bacon instead of ham. Our phyllo sheets measure about 14 x 16 inches, which are enough for 9 muffin hollows. Four sheets will give you a nice firm cup shape. Dressing should be added, if at all, at the last moment to prevent sogginess.
