Since I've found myself in a city with limited options in terms of good Asian food, I've been doing a bit of experimenting in my own kitchen. This beef had great results - flavorful and tender.
1 ½ lbs tri-tip steak, trimmed
Marinade:
¼ cup orange juice
¼ cup soy sauce
2 T. sesame oil
2 tsp. brown sugar
1 tsp. ground ginger
3 cloves garlic, finely minced
1 tsp. red pepper flakes
Glaze:
¼ cup orange juice
2 T. orange marmalade
Pierce steak with fork several times on each side. In a small bowl, combine ingredients for marinade; whisk to combine. Pour marinade into large, resealable plastic bag; add steak and shake to coat. Refrigerate 3 hours-overnight.
Preheat broiler for 10 minutes. Remove steak from bag and place on greased broiler pan. Whisk together glaze ingredients; brush over one side of steak. Broil 6-7 minutes per side, until medium-rare; flip once and coat the reverse side with glaze. Let rest 5-10 minutes, then slice thinly on a bias.
