Begin by finely chopping the sweet onions. Remove excess moisture with a paper towel.

In a large mixing bowl, combine softened cream cheese and sharp cheddar cheese. Mix until creamy and well blended.

Add pimentos, garlic powder, and Worcestershire sauce, stirring until all ingredients are mixed well.

Gently fold in the chopped onions, ensuring they are evenly distributed.

Cover the bowl with plastic wrap or transfer to an airtight container and chill for at least 1 hour.

Stir before serving and scoop into a serving dish. Serve with crackers or veggies.
