Budget-friendly flank steak is best when marinated then cooked on a hot grill to sear in the juices. Serve with a fresh pineapple and bell pepper salsa.
Mix 1/2 cup of the marinade and cilantro in small bowl. Place steak in large resealable plastic bag or glass dish. Add marinade mixture; turn to coat well. Refrigerate 30 minutes or longer for extra flavor.
Meanwhile, for the Pineapple & Bell Pepper Salsa, place all ingredients in medium bowl; toss gently. Cover. Refrigerate until ready to serve. Remove steak from marinade. Discard any remaining marinade.
Grill steak over medium-high heat 7 to 8 minutes per side or until desired doneness, brushing with remaining 1/4 cup marinade halfway through cooking. Let stand 5 minutes before slicing. Serve steak with Pineapple & Bell Pepper Salsa.
