When pan is very hot, carefully place the steak. Cook 3 minutes without touching then flip. When you leave the steak without moving it around, it builds a nice crust. Cook 3 minutes on other side.
Let steak rest for 5 mins.
Add more oil to pan if there isn’t any left. Bring to medium-high heat and add onions and peppers. Cook for 7 mins until veggies are soft.
While veggies are cooking, add parsley, garlic, tomatoes, olive oil, lemon juice, salt and pepper to a bowl and mix.
Cut a slit in your pita at the top and open it up with your fingers and stuff it up with as much good stuff as you can! More tahini the better!
