Here in Austin,TX and other Texas areas there's a restaurant called El Polio Regio.. They have this hot sauce that they give with each order that I'm very fond of.. It's amazing! The restaurant uses Monterrey, Mexico recipes..
The HOT sauce they give is a green spicy salsa... It doesn't have the typical green salsa look, jalepeno or green tomatoes.. It has a white country gravy consistency.. but a with a green tint.. It's a puree so I cant put my finger on the ingredients.. I'm thinking it's either mayo with a jalepeno puree or a creame....with avocado.. I could be wrong!! Any help with be great
