Cut chicken breasts and bell peppers in appropriate sized strips then separate them.

Mix the shawarma flavouring powder with the chicken and then mix with bell peppers, resulting in one whole mixture. Then spray with sunflower oil everywhere.

Set your cooking device for 200°C for 25min and cook shawarma mixture, leave it cooking while preparing other ingredients.

Cut lettuce into small pieces, you can season it if preferred. If you have any other things you wanted to cook along with the shawarma wrap, cook now.

Collect the shawarma mix from cooking device after 25min and place it in the flatbread along with the lettuce and sauce. Wait till the shawarma wrap is completely warm and then ready to eat.
