Marinate the chicken with turmeric paste and salt for 15 minutes.
Fry the chicken in an �air-fryer�, to reduce oil and fat.
Grind onion, ginger, garlic and chilli. Saute this mixture of ingredients in vegetable oil over medium heat until fragrant. Then, add the diced tomatoes and tomato sauce.
Put water into the stir -fry and cook over high heat.
Once the gravy starts to boil, return the heat to the lowest and let it cook. When the gravy has thickened, add the fried chicken and stir well.
Then, it is ready to be served.
