This recipe was originally demonstrated on a Disc-It outdoor grill (think of a propane-powered wok on steroids), but you can grill these burgers as well. Read more about the Disc-It and burgers in Mark Masker's article here.
Like most stews, this one takes a while to cook, about 4 hours. It is interesting because it contains a number of pre-Columbian ingredients, namely Chiltepins, corn, squash, potatoes, and tepary beans. The spicy heat can be adjusted by adding or subtracting Chiltepins.
