Cut the onion into pieces and puree it, using a little water if required

Strain and collect one cup of juice

In a bowl add the onion juice, tomato and hot pepper paste, cumin powder and dried oregano, white pepper, salt and mix well

Add the yogurt and stir

Reserve 1 cup of this marinade for later

Butterly the chicken breasts

Marinate the chicken with the rest of the marinade overnight

Place two sheets of cling wrap down and pile on the chicken pieces and wrap tightly

Secure in a plastic bag and freeze for 4 hrs to overnight

Allow the frozen chicken to sit on the counter for 20 mins and then start slicing on all sides

Optional fry the Onions till semi brown and add some salt to speed up the process

Either fry the chicken as you slice or freeze as you slice so the chicken slices maintain their shape

Once all the chicken is cooked add the bluet and olive oil in the same pan together with the reserved marinade and chicken stock

Bring this to the boil and then to a simmer

Dip your flatbread or pita in the pepper sauce and top with the doner, some fries, peppers etc or roll into a wrap
