Heat a kadai and add little oil.
Add the chopped onion and fry till it gets pinkish.
Then add ginger-garlic paste and fry for 1 minute.
Add finely chopped garlic and fry for few seconds.
Next add chopped tomato and fry on low flame by closing the lid of the kadai/pan till the tomato gets mushy.
Add green chili sauce and mix well.
Add the spice powders – cinnamon powder, coriander powder, cumin powder and black pepper powder and mix well.
Add the prepared green paste and mix well. Let it cook for 5 minutes.
Add the chicken pieces. Stir and close the lid of the kadai/pan.
Add stock cube and mix well. (This is optional)
After some time, check if chicken is cooked by trying to cut open a small piece of chicken while it is getting cooked in the kadai. If chicken is cooked properly then you will notice pieces separating easily.
