Combine cream cheese, shredded cheese, sour cream, garlic powder, dried parsley, green onions, and Worcestershire sauce in a bowl. Add two tablespoons of the chopped beef. Mix until the ingredients are well distributed.

Shape the mixture into a round ball using your hands, then wash and dry your hands well to make rolling easier.

Spread the remaining beef out on a baking sheet or parchment paper.

Roll the cheese ball over the dried beef, covering as much of it as you can. Then, use your hands to place any remaining chipped beef over any bare spots.

Chill the cheese ball in the fridge for a few hours to let the flavors meld, then serve with crackers, pretzel crisps, pita wedges, carrot sticks, or Melba toast.
