The correct answer to red or green isn't both, it's "Who's cooking?" I love this stuff so much, it's a big part of why I'm married.
Remember there is a massive difference between New Mexico Chile (red, green, Christmas) and chili aka chili beans as being described in this thread, at least according to my New Mexican wife and family. One really has nothing to do with each other usually. Chile is more of a condiment or way of life than a main dish itself. You can add chiles to your chili, but chili isn't chile. Your recipes are chili beans with chiles in them, not red/green itself.
We either have the greens roasted and sent up from a friend in Deming, or from family in Silver City, or occasionally we'll see hatch green chiles in the local Fred Meyer and roast them ourselves on the grill. We usually keep it frozen and add it a bag at a time to whatever we're making (enchiladas, burritos, burgers, etc).
Reds, we get a gunny sack every time we go visit the family or have a bag shipped up. Recipe in the next post.
