Heat the oil in a pan, add the chopped onion, bay leaf and curry leaves once it starts to shimmer and fry for about 2 minutes.
Add the tomato paste, ⅕ cup water, lemon juice and lemon wedge and cook for about 3 more minutes.
Now add a pinch of sugar and season with salt and pepper to taste, and leave to cool completely.
Strain the sauce through a sieve into a large bowl and stir in the apricot marmalade, mayonnaise and Greek yoghurt for a creamy dressing and add the chopped chicken.
Check the seasoning and add more salt and pepper to taste.
Serve.
