In a large skillet, heat the sesame oil over medium heat. Add the minced garlic and grated ginger, sauté for about 1 minute until fragrant.
Add the ground chicken to the skillet, breaking it apart with a spatula. Cook for about 5-7 minutes until completely cooked and browned.
Stir in the diced red bell pepper and shredded carrots, cooking for an additional 2-3 minutes until the vegetables are slightly softened.
In a small bowl, mix together the Sriracha sauce, soy sauce, and hoisin sauce. Pour this mixture over the cooked chicken and vegetable mixture, stirring well to combine. Let it cook for another 2 minutes to meld the flavors.
Remove from heat and stir in the chopped green onions. Taste and adjust the spiciness if needed by adding more Sriracha.
To serve, carefully separate the lettuce leaves and spoon the spicy chicken mixture into the center of each leaf.
Garnish with toasted sesame seeds and fresh cilantro.
Notes
Adjust the amount of Sriracha sauce to suit your spice preference.
