Boil the chicken breasts thoroughly.

After boiling, cut the chicken into small pieces.

In a pot, sauté a grated onion, then add the chicken and stir. Add all the spices (feel free to add more if you like) and mix well until everything is combined. Turn off the heat.

Take a round tortilla, lay it flat, spread mayonnaise in the center, add the chicken mixture on top, and roll it up like a sandwich.

Heat a griddle or skillet over the stove. Once hot, lower the heat, place the shawarma on it, and press it down until it browns slightly. Flip and brown the other side as well.

Cut the shawarma into pieces as desired.
