Preheat oven to 350°. In a large bowl, combine first six ingredients. Stir in cheese, ham and cranberries. Spritz one side of each wonton wrapper with cooking spray. Gently press into miniature muffin cups, coated side up. Spoon 1 tablespoon cheese mixture into each.
Bake 10-14 minutes or until crusts are golden brown. Sprinkle with fresh chives if desired; serve warm. Refrigerate leftovers.
