There is an 8 hour chilling and marinating time, so you can make this ahead of time. That 8 hours is not included in the prep or cooking time. Once you do all the work ahead of time, the steak only needs to cook 4-6 minutes per side.
2Place steak in a large shallow dish, and set aside.
3Combine the orange juice and the next 10 ingredients in a small bowl; stir well. Pour the marinade over the steak. Place the orange slices over the steak. Cover and marinate in the refrigerator for 8 hour, turning the steak occasionally.
4Remove the steak from the marinade, and discard the marinade. Grill the steak over hot coals for 4 to 6 minutes on each side or to the desired degree of doneness. Let rest 10 minutes.
5To serve, slice the steak diagonally across the grain into slim slices. Serve with the Fresh Fruit Salsa, garnish if desired with orange wedges and fresh cilantro sprigs.
6For the Fresh Fruit Salsa:
7Combine the pineapple, papaya, kiwifruit, sweet red pepper, green bell pepper, white wine vinegar, minced cilantro, sugar, and crushed red pepper in a bowl; toss gently. Cover and chill for 8 hours. Let stand at room temperature before serving.
