Start by preheating your Teppanyaki grill to medium-high heat. The key to this recipe is to achieve a beautiful char on the lettuce while keeping it fresh inside.
While the grill is heating up, prepare the lettuce. Cut each head of Cos lettuce in half lengthwise, leaving the root intact to hold the leaves together.
In a small bowl, whisk together the olive oil, soy sauce, minced garlic, and a pinch of salt and pepper. This flavorful dressing will elevate the taste of the lettuce.
Brush the lettuce halves generously with the olive oil mixture, ensuring the leaves are well-coated. This will help them caramelize beautifully on the grill.
Place the lettuce halves on the Teppanyaki grill, cut side down. Cook for about 2-3 minutes until the edges char and the lettuce wilts slightly, but still maintains its freshness.
Carefully flip the lettuce using tongs and grill for an additional 2 minutes on the other side. The goal is to create a balance between smoky char and the crispness of the lettuce.
Once grilled to perfection, remove the lettuce from the grill and place it on a serving platter.
Drizzle any remaining dressing over the charred Cos lettuce and sprinkle with sesame seeds for added texture and flavor.
Serve immediately with zesty lemon wedges on the side for a bright, citrusy touch.
