Thanks NaMaan 
Thanks mano87.
i used maggi Manchurian secret for this.
only what i have to do is cut boneless chicken in small pieces and marinate it with salt, black pepper and cornflour. then fry it till light golden brown.
add 2 table spoon of oil in pan and add ginger garlic paste, green pepper and fried chicken in it. fry for 2 mins then add 2 table spoon of ketchup and 2 table spoon of vinegar. cook for 2 minutes. add maggi manchurian secret packet in approx 1 cup of water and add in the pan. cook on low flame for few minutes or till u get the desired color.
i love dhaniyaa
