Yakiniku is not just about the meat; it's also about the variety of vegetables that accompany the grilled meat. Some popular choices include cabbage, lettuce, bean sprouts, mushrooms, bell peppers, and onions. These vegetables provide a refreshing and crunchy texture that complements the rich and savory flavors of the grilled meat. You can also add other vegetables like zucchini, asparagus, or eggplant for more variety. It's important to cut the vegetables into bite-sized pieces so that they cook quickly and evenly on the grill. You can either grill the vegetables alongside the meat or serve them raw as a salad.
