Prepare a grill fire to about 350° with hickory or oak for smoke flavor.

Wash potatoes and place in a pan, cover with water and bring to a boil. Cook for about 10 minutes or just until tender enough to pierce with a fork. Drain and set aside.

Cut onions into bite size pieces and slice potatoes in half. Place in a bowl and drizzle with 3 tablespoons olive oil, mix to coat.

Season potatoes and onions with 2 tablespoons of dry rub, mixing well.

Cut steak into 1 1/2 - 2 inch cubes drizzle with remaining olive oil and season with remaining dry rub.

Thread steak, potatoes and onions onto skewers.

Cook over indirect heat with the the grill closed about 10 minutes.

Do not turn the kabobs. Check internal temperature of steak with a digital thermometer and cook until desired doneness is reached. We cooked ours to about 140° for medium.

Remove from grill and and allow to rest for 5 minutes before serving.
