In a large skillet, heat the sesame oil over medium heat.
Add the ground chicken to the skillet and cook until browned, about 5-7 minutes, breaking it apart with a spatula.
Stir in the minced garlic and grated ginger. Cook for an additional 1-2 minutes until fragrant.
Add the chopped red bell pepper and water chestnuts to the skillet. Cook until the peppers are tender, about 3-4 minutes.
In a small bowl, whisk together honey, soy sauce, and rice vinegar. Pour this mixture over the chicken and stir well to combine. Cook for another 2-3 minutes, allowing the sauce to thicken slightly.
Season with salt, pepper, and sprinkle sesame seeds over the mixture. Stir gently.
Remove the skillet from heat and add the sliced green onions, mixing them in.
To serve, spoon the chicken mixture into the butter lettuce leaves, forming wraps.
Notes
Arrange the lettuce wraps on a large platter, garnished with extra sesame seeds and green onion slices for color. Serve with additional honey on the side for drizzling!
