Well, I'm just taking a wild stab here, but _The_Whole_Chile _Pepper_Book_ has a recipe for Papas a la Huancaina that is a dish of boiled potatoes topped with cheese and a sauce that is probably light green and creamy. Here's the sauce part: <Curtis> cjackson@mv. Us. Adobe. Com

Combine 2 Aji' or 3 Jalapen~o chiles, stems and seeds removed and chopped, 1 cup queso blanco or Munster cheese, and 1 cup heavy cream in a blender and puree until smooth. Heat 2 tablespoons of olive oil and slowly add the cheese mixture, stirring constantly. Simmer the sauce for 5 minutes or until it thickens.

If the sauce you remember didn't have cheese in it, try omitting it.
