Chiles are a staple in Southwest cuisine, and Hatch Valley chiles are among the most popular. They come from the Hatch Valley in New Mexico, and people turn them into green sauce. The sauce is popular in both New Mexico and Arizona.
There’s also red chile sauce, and when ordering New Mexican food, you’ll be asked if you want green chile, red chile, or Christmas, which is both green and red.
