I found this recipe in Cuisine Lite and my whole family loved it! And it's low-cal! I think you could have one and a halved the marinade so that there was more for the steak to soak in, but it was good regardless
Blend hoisin, broth, vinegar, garlic, sesame oil, brown sugar, soy sauce, ginger, and Sriracha in a blender, or food processor until smooth.
Score one side of steak in a diamond pattern, then place in a resealable plastic bag. Pour all but 1/2 cup sauce into bag, turn steak to coat, and marinate at room temperature at least 20 minutes. (save remaining sauce to use in Snap Pea Noodle Salad).
Preheat grill to high.
Remove steak from marinade, season with salt and pepper, and grill, covered, 5 minutes. Turn steak over and grill to desired donesness.
Transfer to cutting board and let rest 5 minutes before slicing thinly against the grain.
