Marinate the chicken with soya sauce, ginger garlic paste, pepper and red chilli paste for minimum of one hour. Marinating it for longer would make the chicken more tender.

In a wok, heat oil. Add the chicken along with all the marination and cook on medium high flame for around 10 minutes, stirring occasionally.

Sprinkle in the chilli powder and vinegar and mix well.

Add the chopped garlic and tomato ketchup and cook for five minutes.

Finally add the chopped spring onion, reserving some greens for garnishing, along with salt and pepper per taste and give it a final mix.

Cook for another five minutes, the chicken would be done by now.

Switch off and serve warm as a starter or as main for chapathis, after garnishing with the reserved spring onions greens.
