Begin by placing 2.5 lbs of beef flanken ribs in a large mixing bowl.
Add 2 tablespoons of chopped green onions to the bowl for a fresh, aromatic flavor.
Include 1 tablespoon of minced garlic for a hint of pungency.
Drizzle 1 tablespoon of sesame oil over the ribs to enhance their flavor and tenderness.
Pour the entire 16.9 oz jar of Bibigo Korean marinade over the ribs, ensuring even coverage.
Use your hands or tongs to mix the ribs with the marinade, garlic, sesame oil, and green onions thoroughly.
Allow the ribs to marinate for a minimum of 30 minutes, giving time for the flavors to infuse into the meat.
Preheat your grill to a high temperature, ready for searing the ribs.
Once the grill is hot, arrange the marinated ribs on the grill.
Grill the ribs for approximately 3 minutes on each side, aiming for a nicely charred exterior while keeping the interior moist and tender.
After grilling, immediately transfer the ribs to a serving platter.
Garnish the cooked ribs with a sprinkle of sesame seeds and a handful of freshly chopped green onions for an added layer of flavor and texture.
