Found this a while back, made it again last night...oh, man.
I've set this up to make 8 servings. I usually only make 4, but do as you will.
2 lbs (4 breasts) chicken, cut in half
1 package taco mix
1/3 cup cornmeal
1-6oz can green chiles (chopped or whole)--I found chopped works better
8 oz jack or mexican "mix" cheese--again, grated works better
2 tbsp fresh cilantro, chopped
Preheat oven to 350.
Mix together taco mix and cornmeal.
Using meat mallet, pound chicken breasts until they are less than 1/4" thick. On each piece of chicken, place on cilantro, chiles, and cheese. Roll up breasts and pin with toothpick. Roll breasts in cornmeal/taco mix until well coated.
Place chicken breasts on cookie sheet or baking pan and bake for 30-35 minutes, or until internal temp is 165 degrees.
My particular favorite is just Mexican rice. Keep it simple.
