Prepare the Marinade: In a large bowl, combine the soy sauce, furikake, chopped lemon balm stem, grated ginger, chopped scallions, matcha powder, and spicy sauce. Mix well to combine.
Marinate the Beef: Place the cubed beef tenderloin in the marinade and toss until evenly coated. Cover the bowl and refrigerate for at least 1 hour, allowing the flavors to infuse into the meat.
Preheat the Grill: Preheat your grill to medium-high heat, about 375°F to 400°F (190°C to 200°C).
Assemble the Kebabs: Thread the marinated beef cubes onto skewers, leaving a little space between each piece to ensure even cooking.
Grill the Kebabs: Place the assembled kebabs on the preheated grill and cook for about 4-5 minutes on each side, or until the beef reaches your desired level of doneness.
Serve: Once the kebabs are cooked to perfection, remove them from the grill and transfer them to a serving platter. Serve hot with your favorite side dishes, such as rice, grilled vegetables, or a fresh salad.
Enjoy: Dig into these delicious Green Beef Kebabs and savor the flavorful combination of tender beef infused with the aromatic blend of soy sauce, furikake, matcha, and spices.
