How can I grill sirloin tips to perfection?

To grill sirloin tips to perfection, start by marinating the meat for at least 30 minutes to enhance flavor. Preheat the grill to medium-high heat and sear the sirloin tips for 4-5 minutes on each side. Use a meat thermometer to ensure the internal temperature reaches 145F for medium-rare or 160F for medium. Let the meat rest for a few minutes before serving to allow the juices to redistribute. Enjoy your perfectly grilled sirloin tips!
