Add the meat to the bowl with the spices, toum, lemon juice, and olive oil. Use your hands to rub the spices into the meat, coating the meat in the spices.
2 pound top sirloin steak or beef tenderloin fillet, 1/3 cup garlic dip, 2 Tablespoons olive oil, Juice of 1 whole lemon, 1 teaspoon cumin, 1/2 teaspoon coriander, 1 teaspoon smoked paprika, 1 teaspoon sea salt, 1/2 teaspoon black pepper
If using bamboo or wooden skewers, soak them in water for at least one hour to prevent sticking. Cut the onion and bell peppers into pieces that are roughly the same width as the meat.
Lightly oil the grates of a gas grill, and heat for 10 minutes on high.
Thread the meat, onion pieces and bell peppers onto the prepared skewers. Alternate using all the meat.
1 large red onion, 2 green bell peppers, 2 red bell or orange bell peppers
Place the shish kabobs on the grill. Cook, turning occasionally and brushing the meat a couple of times with the marinade as it cooks. The steak skewers will be done in 8 to 10 minutes, depending on how hot the grill is and how well-cooked the meat is preferred.
