To make your marinade, combine, greek yoghurt, tandoori masala, garam masala and salt. Place your chicken thighs in the marinade and set aside for 1 hour.
For the coronation chicken sauce, combine mayo, chutney, yoghurt, curry powder, lemon juice, apricots and worcester sauce until smooth. Taste for seasoning.
Once your chicken has marinated, combine flour, salt, garlic powder, curry powder, cayenne pepper and tandoori masala in a large bowl. Dredge your marinated chicken thighs in seasoned flour and carefully deep fry until crisp and golden brown. Once your chicken has cooked through, remove from oil and place on a rack, dust with tandoori masala for an extra boost of flavour.
To make the salad for your burgers, toss together, sliced spring onions, gem lettuce, green chilli, coriander and a squeeze of lime juice.
Assemble your chicken burger, with coronation sauce on the base of the bun and a small squeeze on the top, then your crispy chicken and salad!
