In a bowl, add cream cheese and stir vigorously until softened.
Add mayonnaise, sour cream, pimentos, shredded cheese, Tabasco, and Worcestershire. Season with salt and pepper to taste.
Transfer dip to an oven-safe serving bowl or container and top with additional cheese.
Bake at 350 degrees F for 20 minutes or until brown and bubbly. You may also choose to broil on high for 3-4 minutes after cooking for an extra bubbly and crusty topping. Serve with crackers.
I use reduced fat or low-fat (but not fat-free) sour cream, mayonnaise, cream cheese, and cheese in virtually everything I make (this recipe included) to cut back on calories. I don't notice a difference in taste using these vs. full-fat versions; however, you're welcome to use whatever suits your taste.
