Beat the cream cheese in a mixing bowl until creamy and smooth. Add in the bacon, green onions, Worcestershire, garlic powder, salt and pepper. Chop the pecans and place onto a single layer on a cookie sheet. Using a mini cookie scoop, drop the rounded balls of cream cheese into the pecans, rolling to completely cover. Place a single pretzel stick into the center of each cheeseball. Chill in the refrigerator until ready to serve- at least a couple of hours to allow the cream cheese to re-harden. Serve with assorted party crackers, or additional pretzel sticks and garnish with a bit more green onions. Makes approximately 10-12 mini cheeseballs.
