It's a salsa or taco sauce. If i recall, ortega is technically a picante sauce. I think the word means "mild" but I don't know 100%. If you're ever confused by an ingredient, and the substitutions list doesn't pop up when you click on an ingredient in these recipes (this one had no alternatives), google it and ignore any AI generated response as the very first result- they are notoriously wrong and in some cases can cause lethal damage!!
