Yum, perfect for Father's Day or any warm, summer night! Be sure to leave the skewers on the grill long enough to get the beef nice and crusty on both sides. This means you have to be patient, and remember: Don't turn them often. Can also add grape tomatoes, mushrooms and chunks of red onion to the skewers. Sometimes I grill the veggies on separate skewers because they can cook quicker than the meat. Then I put all on a platter and let guests choose what they want. Plan ahead, needs to marinade for 30 minutes up to 4 hours. This is adapted from a Bobby Flay recipe. Prep time does not include marinade time.
