Classic Yakiniku is a popular Japanese grilled meat dish that is perfect for gatherings and barbecues. The main ingredients for this recipe include thinly sliced beef, such as ribeye or sirloin, and a variety of vegetables like onions, bell peppers, and mushrooms. To make the marinade, you will need soy sauce, mirin, sake, sugar, garlic, and ginger. The meat and vegetables are marinated in the sauce for at least 30 minutes to allow the flavors to infuse. Once marinated, they are grilled over high heat until they are cooked to perfection. The result is tender and juicy meat with a delicious smoky flavor. Serve the grilled meat and vegetables with steamed rice and a side of dipping sauce for a complete meal.
