This recipe comes from the back of a label of Montera Picante Sauce, dated 1982. Recipe is typed below along with a scanned copy (the type is really faint on the clipping).

1 jar (8 oz.) Picante Sauce
1 1/4 cups cubed American or processed cheese
3/4 cup shredded Monterey Jack cheese
3/4 cup shredded sharp Cheddar cheese
3 tablespoons milk
1 tablespoon butter or margarine
1/8 teaspoon garlic powder
Pepper, to taste
Tortilla chips
In a medium saucepan, combine 2/3 cup sauce with remaining ingredients except tortilla chips. Stirring frequently, simmer 10-15 minutes or until cheese is smooth and heated through. Top with remaining sauce. Serve with tortilla chips.
