Preheat grill pan over high heat. Season steak with salt and pepper. Spray grill pan with cooking spray. Grill meat 3 to 5 minutes per side for medium rare to medium well doneness. Remove meat and let stand 10 minutes.
In a pan, bring 1-inch of water to a bubble. Add a pinch of salt and broccoli pieces and steam for 3 to 5 minutes, until cooked but still firm. In the sink, drain broccoli in colander and run cold water over it to cool.
Arrange greens on large platter or individual dinner plates. Arrange broccoli and veggies on greens. Combine duck or sweet and sour sauce with ginger, lime juice, vinegar, crushed pepper flakes. Whisk in oil. Slice steaks and arrange on salad and drizzle completed dish with dressing. Season with additional salt and pepper.
