Heat a very generous lug of oil in a pot big enough to cook your pulao in
Add the onions and cook on medium heat till amber
Now add the chicken and saute until the pieces are all white
Add all the remaining pulao masala ingredients except the green chillies
Mix well, saute on medium high heat for two minutes
Let the masala come to a boil, then simmer on low until the chicken is done. The chicken releases it's own liquid so you shouldn't need to add any unless the masala seems like it will stick/burn.
When the masala is ready the oil will have risen to the top and the chicken will be tender. This can take anywhere between 25-35 minutes depending on your chicken.
Once the chicken is done add the rice, green chillies, and 3.5 cups of water to the pot along with 1.5 tsp salt
Mix well and taste, it should be just a little salty.
Bring the pulao to a boil and cook partially covered until almost all the water has evaporated then close the lid completely for 5-8 minutes until the remaining moisture has absorbed and the rice is done.
Gently fluff the rice from the sides and serve with your chutney/raita/achar of choice
