Grilled Persian Beef Kabobs

Cut the beef into small, uniform pieces approximately 1 inch by half an inch in size and place them in a large container. Add the diced onion, freshly squeezed lime juice, salt, and black pepper; thoroughly combine the ingredients. Cover the container and refrigerate it for a prolonged period of 8 hours or overnight to allow the flavors to meld.

Prepare an outdoor grill for high heat and lightly brush the grill grates with oil to prevent sticking.

Alternate pieces of beef on skewers, filling each one with 6 to 8 cubes. Discard any remaining marinade.

Cook the beef skewers on the preheated grill for 3 to 4 minutes per side, resulting in a total cooking time of 12 to 16 minutes. Use an instant-read thermometer inserted into the center of the beef to verify that it has reached a minimum internal temperature of 145 degrees F (63 degrees C).
