For making chicken kali mirch
In a wide pan, lightly heat up 2 tablespoons of oil, and to it add 1 teaspoon of black mustard seeds.
When the mustard seeds start crackling, add in 10 curry leaves, and 2 red chilies (each slit in two parts), and roast for 1-2 minutes, till they get lightly roasted.
Then add in 1 cup of chopped onions & ½ teaspoon salt, and saute on medium flame, till the onions start to turn light brown.
After this, add in 2 tablespoons of ginger garlic paste & saute for a couple of minutes, just till it loses its raw flavor.
Finally add in the marinated chicken thigh pieces & mix well.
Cook covered on medium high heat, stirring intermittently, till the chicken is fully cooked ( ~ takes about 20-25 minutes).
Serve this chicken kali mirch / pepper chicken hot.

Notes
You can adapt this recipe to make chicken kali mirch using bone-in chicken too. But if you are using boneless chicken, then it's best to go with thigh meat, and not breast meat, for a juicier pepper chicken.
