Begin by marinating the steak. In a bowl, combine soy sauce, sesame oil, garlic, and ginger.
Place the steak in the marinade, ensuring it's well-coated. Let it marinate for at least 30 minutes.
Preheat your grill over medium-high heat.
Chop the assorted vegetables into bite-sized pieces.
Remove the steak from the marinade and season with salt and pepper.
Drizzle vegetable oil on the grill to prevent sticking.
Place the steak on the grill and cook for about 4-5 minutes on each side for medium-rare.
Add the vegetables to the grill during the last few minutes of cooking.
Remove the steak and vegetables from the grill once done.
Let the steak rest for a few minutes before slicing, then serve with grilled vegetables and lemon wedges.
