Chicken Shawarma

1. Cut boneless chicken breasts in to bite-sized pieces and marinate in vinegar overnight.(Can add step 3 in the marinade too)
2. Prepare the tahini: toast sesame seeds on pan (do not brown). Put in coffee grinder and grind to powder. Add olive oil in a bowl and mix. Set aside
3. Heat crushed garlic,salt, pepper and spices (like cardamom pods, allspice) or shawarma mix to the chicken and cook until soft in a wok. (Assuming you don't have a vertical spit to grill it for a day)
4. Add bell pepper , onions and tomatoes.(I like them lightly fried) 
5. (You can shred the chicken if you want)
6. Place a tortilla or pita(heat both sides if you want), fill with the chicken and tahini sauce. You can add sliced  cucumbers and/or pickles.
7. Serve with hummus and salad greens.
