In a mixing bowl, combine soy sauce, olive oil, minced garlic, honey, and black pepper.
Place the flank steak in a resealable plastic bag and pour the marinade over the steak. Seal the bag and refrigerate for at least 2 hours, or overnight for best results.
Preheat your grill to high heat. Remove the steak from the marinade and discard the marinade.
Grill the steak for about 4-5 minutes per side, or until it reaches your desired level of doneness.
Let the steak rest for 5 minutes before slicing against the grain. Serve and enjoy!
