My grandma always made stuffed celery at Thanksgiving and Christmas. As kids, we were always so hungry before the holiday meal we would sneak and get a piece of celery to curb our appetite. It was nearly all gone by meal time and we always got fussed at with hint of a grin from Grandma. Now I never have holiday meals without it!
Thoroughly dry each piece of celery with paper towels. Mix the cream cheese, olives, garlic, salt, and black pepper in a bowl. Using a knife, spread a generous amount of cream cheese filling down the center indentation of each celery piece. Serve immediately or refrigerate.
