In a large skillet over medium heat, add the ground chicken and cook until browned, about 5–7 minutes, breaking it apart as it cooks.

Add the chopped onion and cook for an additional 2 minutes until translucent.

Stir in hoisin sauce, soy sauce, and minced garlic until well mixed and heated through.

Remove from heat and spoon the mixture into washed lettuce leaves, serving with cilantro and lime.
