In a small bowl, whisk together hoisin sauce, soy sauce, rice vinegar, honey, sesame oil, grated ginger, minced garlic, and red pepper flakes.
Heat a large skillet over medium-high heat. Add the chicken and cook until browned and cooked through, about 5-7 minutes.
Pour the sauce over the cooked chicken and stir to coat. Cook for an additional 2-3 minutes until the sauce thickens slightly.
To assemble the lettuce wraps, place a scoop of the chicken mixture onto each lettuce leaf. Top with chopped green onions, cilantro, chopped peanuts, and a squeeze of lime.
Serve immediately and enjoy!
