Peel the garlic and onion, and add them to a food processor together with the ginger puree, and blitz until finely chopped.
Heat up the oil in a pan, and add the onion mixture.
Fry until golden, then add the turmeric, garam masala and cumin, and give it a stir.
Fry for 2 minutes so the spices can release their flavours, then pour in the tomato passata and chicken broth/stock.
In go the cubed leftover turkey, and leave to cook with the lid on until the sauce is reduced and thickened.
Add the yogurt and chopped coriander/parsley, season to taste with salt and pepper, and serve hot.
Take off the heat, and serve hot with rice or flat bread.
