BTW, New Mexico is the only state in the US that has an "official state question." It is, and you will get this asked in many restaurants, "red or green?" This refers to the color, flavor and degree of hotness of the chili sauce (and, as Sorcha said, it resembles gravy more than anything else) that you want on your meal. Adventurous souls looking for a challenge reply "Christmas," and get both. Wimps and Texans say "on the side."
