Make these crepes for a special brunch, lunch, or dinner. The crepes are a great way to use leftover ham, but feel free to use deli ham if that's what you have. If you need to cut corners, use your favorite brand of alfredo sauce instead of the homemade parmesan cheese sauce. Plan to make the crepe batter at least an hour ahead of time, or refrigerate the batter for up to 24 hours.
