Make the spice rub by combining the cumin, garlic powder and salt in a small bowl.
Lay the steaks out on a work surface. Sprinkle enough of the rub to lightly coat one side of the steaks, then rub the spices into the meat. Turn the steaks over and repeat the process.
Let the steaks sit at room temperature for 10 to 15 minutes.
Place the steak on the grill, and grill covered on direct heat for 7 minutes. Turn the steaks over, and grill for another 6 minutes. Check for doneness–at this point, our ribeye steaks were a perfect medium rare. Adjust your cooking times based on your grill and desired doneness, keeping in mind the steak will cook a bit more while resting.
When the steaks are done grill, remove to a large platter and let rest for a few minutes. Slice the steak against the grain, and plate four or five strips of the steak on each plate. They can always ask for seconds! Enjoy!
