This may be more my California roots, than my Southern ones, but it has been on the Clanton snack table at Thanksgiving and Christmas sent 1945. It is not Guacamole and is best with potato chips.
2 large avocados, soft ( California Hass )
1 package cream cheese, softened
4 ounces mayonnaise
dash of lemon or lime juice
1 teaspoon seasoned salt
Peel, remove seed and mash avocado. Mix with next 4 ingredients. Serve with chips. If it needs thinning add a little milk.
