We did chicken in green chili sauce tonight. Pretty basic but tasty as hell.
1 lbs of chicken breast
4 cups chicken stock
1 tbsp oil
5 tomatillos, remove the outer leaves and the stems
4 gloves of garlic
4 serrano chiles, membrane and seeds removed
4 sprigs of cilantro
salt to taste
Put the chicken and the stock in a slow cooker on high for 4 hours. Flip the chicken every hour.
When the chicken's done set it aside and let it rest for 20 minutes. Reserve the cooking liquid.
Put the tomatillos into a pot and cover with the cooking liquid from the chicken. Bring to a boil, cover, and reduce to low. Let it simmer for 15 minutes.
Remove the tomatillos with a slotted spoon and put them into a blender. Reserve the cooking liquid. Add the garlic, chiles, and cilantro to the blender. Blend until smooth.
Add the oil to a pan over medium-low heat. Add the tomatillo mixture and cook for 10 minutes. Stirring occasionally. Taste it and add salt to taste.
Shred the chicken and add to the pan. Add cooking liquid as necessary to make it saucy.
