Don't use the pre-shredded cheese. I like to shred one cheese or the small side of the grater and the other on the large side. It's just a personal preference, but makes a difference in the texture. Mix grated cheeses with cream cheese, mayonnaise, and next four ingredients. Stir to combine well. Serve immediately. Refrigerate any unused spread.
Try these options: Grilled Pimento and Cheese, on a hamburger, heated and served as a dip.
Variations: add 1/2 chopped pecans and 1/2 diced pepperoncini or jalapeno peppers
