In a bowl, whisk together the sesame oil, rice vinegar, oyster sauce, sweet rice wine, and soy sauce. Set aside. This marinade is key—it adds layers of flavor right from the start.
In a large skillet, heat the canola oil over medium heat. Add the ground chicken, cooking until it turns white, about 5 minutes. Break apart the chicken to ensure even cooking.
Once the chicken is cooked, stir in the minced garlic, grated ginger, diced mushrooms, and chopped water chestnuts. Sauté for an additional 3-5 minutes, allowing the flavors to meld together.
Pour your prepared marinade over the chicken mixture. Stir well to coat everything in that delightful sauce. Cook for another 2-3 minutes, until it’s heated through and fragrant.
Take your lettuce leaves and spoon a generous amount of the chicken mixture into the center. Don’t overfill or you’ll have a mess! Top with sliced green onions for an extra burst of freshness.
To create your special sauce, combine the chili oil, hot mustard paste, chili garlic sauce, rice vinegar, soy sauce, and sliced green onions in a small bowl. Adjust the heat to your preference.
Plate your stunning lettuce wraps alongside the special sauce. Dive in and enjoy the crunch and flavor. Go ahead—dare to make a mess!
