To make the marinade, combine the finely chopped onion, garlic, chili, and parsley with lemon juice, olive oil, salt, and pepper. Thinly slice the rib-eye steak into strips and leave to marinate.
In a medium size pan over medium heat, heat ½ tablespoon olive oil. Add the beef stripes and cook until browned, about 5-7 minutes.
For the hummus, place all the ingredients in a blender and process until it has a smooth texture. If the mixture is too thick, gradually add water until you get the desired consistency.
Quickly fry the tortilla over an open flame and drizzle a few drops of olive oil on top.
