Place the flank steak in a large resealable plastic bag or a shallow baking dish.
Crush the peppercorns with a mortar and pestle or the bottom of a heavy skillet, ensuring they remain coarse for maximum flavor.
In a small bowl, whisk together Dijon mustard, crushed peppercorns, minced garlic, olive oil, soy sauce, red wine vinegar, and salt until well combined.
Pour the marinade over the flank steak, ensuring it is evenly coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, preferably overnight for best flavor.
When ready to cook, remove the steak from the refrigerator and let it come to room temperature for about 30 minutes.
Preheat a grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
Remove the steak from the marinade, allowing excess to drip off. Grill the steak for 5-6 minutes per side for medium-rare, or adjust cooking time to your desired doneness.
Transfer the cooked steak to a cutting board and allow it to rest for 10 minutes to retain its juices.
Slice the steak thinly against the grain for maximum tenderness.
Garnish with freshly chopped parsley, if desired, and serve immediately. Pair with a side of roasted vegetables or a crisp green salad for a complete meal.
