Directions Marinate beef with onions, garlic, 7 spices, olive oil, lemon juice and salt for at least 4 hour (overnight is preferred). After marinating, place the beef in a baking tray and cover with aluminum foil. Bake in a preheated oven for 400 degrees for at least 20 minutes. After 20 minutes, remove the foil and drain the juices. Place it back in oven uncovered and bake for another 12-15 minutes (until it is nicely browned). Remove from oven and allow to cool down for few minutes. Evenly distribute the beef in the middle of middle Pita bread. Add the toppings and tahini sauce. You can also add chili sauce if you want spicy shawarma. Heat before serving and Enjoy!
