Enjoy summer grilling with these Steak Lettuce Cups filled with marinated jerk sirloin and tropical mango. They're so easy to make, fresh, bright, and healthy!
Combine beef and the marinade in a large plastic bag; toss to coat. Place in refrigerator overnight.
Preheat a grill to medium-high heat; coat the grates with oil well.
Place the steak on the grill and cook until golden brown and slightly charred, 4 to 5 minutes. Turn the steaks over and continue to grill 3 to 5 minutes for medium-rare (an internal temperature of 135 degrees F), 5 to 7 minutes for medium (140 degrees F) or 8 to 10 minutes for medium-well (150 degrees F).
Thinly slice against the grain.
Fill lettuce leaves with steak strips and mango; drizzle with some of the meat juices and top with diced scallions.
