For the Relish, mix all ingredients in medium bowl. Set aside.
For the Steak Skewers, brush steak with oil, then sprinkle with McCormick® Grill Mates® Montreal Steak Seasoning. Alternately thread bell pepper, steak cubes, red onion and apricot onto 8 skewers.
Broil or grill over medium-high heat 8 to 12 minutes or until steak is desired doneness, turning occasionally. Serve skewers with Tomato Olive Relish.
