Shawarma is a middle eastern spiced beef or chicken sliced thinly with fresh veggies and tahini sauce (also known as tarator) or garlic aioli for the chicken. It is one of the most well-known Lebanese cuisines.
Begin by slicing your beef into 3-inch thin slices. To make the marinade, combine the vegetable oil with the distilled white vinegar. Add the Shawarma spice, salt and black pepper. Mix them thoroughly with the meat and cover with plastic wrap and return to the fridge.
After about 6-8 hours of marinating, the beef is ready to be cooked. Sautée the beef in a skillet on medium-high heat for 10-15 minutes, until most of the juices have evaporated. Taste for seasoning.
Slice all your vegetables for your sandwich or platter (Tomatoes, small Lebanese pickles, pickled turnips)
While the beef is cooking, prepare your Tahini sauce. Crush 1 large or 2 small cloves of garlic with a ½ tsp of salt. Add the Tahini, freshly squeezed lemon juice and water. Whisk until fully combined. Tahini paste has a very strange texture when you first begin to whisk it. You will notice it starts to get thicker and clumpy but, just keep whisking, and it will get silky and smooth.
To make your sandwich, open up a pita and arrange the beef and all your fixings. Drizzle the Tahini sauce on top.
