01 - Whisk together soy sauce, hoisin sauce, sesame oil, rice vinegar, honey, and chili flakes in a small bowl until well combined. Set aside until ready to use.
02 - Heat a non-stick skillet or wok over medium-high heat. Add a splash of oil and sauté ginger and garlic for 30 seconds until fragrant, being careful not to burn them.
03 - Add sliced shiitake mushrooms to the pan and cook for 3–4 minutes, stirring occasionally, until they begin to soften and release their moisture.
04 - Add julienned carrot and sliced bell pepper to the skillet. Sauté for another 2–3 minutes until vegetables are crisp-tender but still retain some crunch.
05 - Pour the prepared sauce over the vegetable mixture. Toss well to coat everything evenly and cook for 1–2 minutes until the sauce thickens slightly and all components are heated through.
06 - Remove the skillet from heat immediately and stir in the sliced green onions, allowing them to wilt slightly from the residual heat.
07 - Spoon the glazed mushroom mixture into individual lettuce leaves. Top with toasted sesame seeds and fresh cilantro leaves just before serving.
08 - Arrange the filled lettuce wraps on a serving platter and serve right away while the filling is warm and the lettuce remains crisp.
