1 lb Velveta (softened or melted)
1 md Size can Pimentos (mashed)
1 ts Sugar
sprinkle of Black Pepper Mix together and add enough mayonnaise or salad dressing to make moist and spreadable (about 1/2 c), adding more sugar for taste. I soften velveda/pimento in micro for 2 min or so, then use Hellman mayo, and sometimes a touch of minced fresh onion.
