Get a clean bowl, put in your ketchup, mayonnaise, chilli sauce, lemon juice and mix to combine.
In a separate bowl put in your cabbage, carrot, green peas, onion, and cucumber and put in almost all the wet ingredients you made (because you’ll use the remaining for your shawarma bread), then mix everything to combine.
After that put in your protein where you have your ingredients mixed together then mix it a little.
Get your shawarma bread, open it and place them together in a way that you can be able to roll it.
Take a little of the wet ingredients you retained and rub on the shawarma bread before proceeding.
Put in your mixed ingredients, your sausage and then your mozzarella cheese, carefully roll it to the shawarma shape.
Put it in a hot pan(low heat) so the bread can stick together.
