Commentary:
Got a Super Bowl party planned? This makes a great party appetizer, perfect in little sandwiches, on crackers, with a sourdough baguette. I took it to a New Year's Eve party, and it was a real hit. People asked what was in it ... and the basic secret is the cumin. I deliberately made this really mild - just the chicken and mayonnaise is very good, and adding cumin and mild green chiles just changes the character, giving it a distinct flavor. It's just got 5 ingredients, and you can tweak it however you want as it's a very forgiving recipe. You could use hot chiles, increase the cumin, or some people will want to increase the mayonnaise - which makes it more easily spreadable, richer tasting, and creamier. Yeah, that means it would be more fattening, too. Note this is a very small batch, so you may want to 2x or 3x it for a get-together.
If you graze on samples at Costco, you may have tried their canned chicken; they always mix it with mayonnaise and spread on crackers when they are sampling it. It's really good, and that's where I got the idea for this. Now I actually did try this with another brand of canned chicken, and that one was inferior. Watch out for off-brands of canned chicken; the Costco brand (Kirkland) is the best of the ones I've tried.
