Pronghorn sirloin roast makes is the perfect vehicle for a flavorful gyro marinade. Grill it and tuck it away in a pita pocket with fresh toppings and a homemade tzatziki sauce for a refreshing summer meal!
If using a sirloin roast, remove silverskin and cut into 3 pieces. To do this, run a boning or filet knife along the seams of the muscles. The meat will naturally separate between the muscles. You should end up with 1 large, 1 medium, and 1 small piece of meat. Once you have separated the muscles, trim off the silverskin.
Combine all marinade ingredients in a glass bowl or container. Add meat and flip a few times to coat. Cover and refrigerate for 2-3 hours.
Preheat grill to 500°F. Cook meat for 5-7 minutes per side or until internal temperature reaches 120°F. Grilling time varies widely based on the size and shape of the meat but an internal temperature of 120°F will lead to medium-rare meat. The smaller pieces will probably be done before the larger piece.
