Better late than never!!! (I only found your request because I, too, had lost my recipe!) One call to mom fixed that, though. Here it is:

ROTEL PIMENTO CHEESE

1 can Rotel, drained
1 cup Hellman's Mayonnaise
1 teaspoon Worcestershire Sauce
1/2 teaspoon salt
2 blocks (8oz.each) sharp cheddar cheese, shredded
1 (4oz.) jar pimento, drained

Stir together first 4 ingredients in a large bowl. Stir in cheese and pimento.

Serve with crackers or on sandwiches.

Yields 2 1/2 cups.
