Wash and cut the chicken into chunks and leave it to drain.
In a pan add your oil of choice and the chopped onion andsaute until translucent. I use olive oil and keep this pan on medium to lowheat throughout the process.
Add the garlic, ginger and chilli and cook for severalminutes.
Add the tomatoes, masala, salt (if needed) and haldi and cook for several minutesuntil everything is combined. This will form the base or sauce of the mixture.I then usually use a hand blender to make the sauce smooth.
Add chicken to the mix and cook. If you would like the baseto be thinner add water whilst cooking the chicken.
Notes
You can replace chicken with lamb chunks of paneer and potatoes.
