Shish Kebab

Make the marinade: In a shallow dish, prepare marinade by mixing olive oil, vinegar, pepper, cumin, coriander, paprika, and garlic. Set aside.

Slice beef into long, thin slices. Then lightly pound the slices with the back of two knives to tenderize the meat. 

Place the beef slices in the marinade and let meat marinate in the refrigerator for 5 to 6 hours before grilling.

Spray flat metal skewers with oil. Take meat out of the refrigerator and thread meat onto skewers. Grill 6 to 7 minutes on each side.
