Preheat a grill or grill pan over medium-high heat.
In a small bowl, whisk together soy sauce, rice vinegar, honey, minced garlic, grated ginger, and sesame oil.
Season the beef slices with salt and pepper, then brush with the soy sauce mixture.
Grill the beef for 2-3 minutes per side for medium-rare, or until cooked to your desired level of doneness. Remove beef from grill and let rest for 5 minutes.
Meanwhile, steam broccoli florets until crisp-tender, about 3-4 minutes.
Slice the grilled beef into thin strips.
In a large bowl, combine the grilled beef, steamed broccoli, chopped green onions, and chopped peanuts.
Drizzle the remaining soy sauce mixture over the salad and toss to combine.
Serve immediately and enjoy!
