Begin by preparing all your ingredients.
Wash and dry the lettuce leaves, ensuring they remain whole for serving.
In a large skillet, heat olive oil over medium heat.
Once hot, add the minced ginger and garlic, sautéing until aromatic.
Add in the ground chicken, breaking it apart with your spatula.
Cook the chicken thoroughly, ensuring there’s no pink left.
Toss in the diced bell pepper and chopped water chestnuts, stirring occasionally.
Drizzle in the soy sauce, hoisin sauce, and sesame oil, blending well.
Add the green onions, giving the mixture a good stir.
Allow to simmer for about 5 minutes, letting all the flavors meld together.
Sprinkle in red pepper flakes if you’re looking to add a kick.
Remove from heat and allow to slightly cool.
