New Mexico--who in God's name puts ham in chili?? ;)
I learned that green chili recipe in Colorado, minus the beans. It's fantastic. I'm a wuss, though, and I usually eat it either over rice or over eggs and hash browns. You can't beat chili over eggs and hash browns. Chili with corn bread (real corn bread, not the sweet kind) is a winner, too.
I'm no purist, though--I grew up with beans-and-tomatoes chili in Colorado, then was introduced to meat-and-meat chili in Texas. I like both.
