Marinate steak tips in sauce for 5 minutes.
Place tips on skewers. Remove any excess marinade.
Preheat grill. If using open flame, wait for flames to die down. Right before grilling, make sure grill surface is extremely hot, then rub it down with an oil-soaked rag – we advise using tongs to hold the rolled-up rag.
For medium, place Sirloin Steak Tips at 45° angle across hottest part of the grill grates, then grill for 5 minutes per side, while rotating 90° every 2 ½ minutes. Keep your meat moving to ensure that it cooks evenly. Remove from grill when meat thermometer inserted into thickest part reads 130°F.
Rest for at least 8 minutes.
