Step 1: Prepare Lettuce : Separate lettuce leaves carefully to avoid tearing. Wash thoroughly and pat dry with paper towels. Refrigerate to keep crisp.
Step 2: Mix the Sauce : In a bowl, whisk hoisin sauce, soy sauce, rice vinegar, sriracha, and honey until smooth.
Step 3: Sauté Aromatics : Heat sesame oil in a large skillet over medium heat. Add onions and sauté for 2–3 minutes until translucent. Add minced garlic and ginger; cook until fragrant (about 30 seconds).
Step 4: Cook Turkey : Add ground turkey to the skillet. Break it apart using a spatula and cook until no longer pink.
Step 5: Add Veggies : Stir in diced red bell pepper and chopped water chestnuts. Cook for 2–3 minutes for a tender-crisp texture.
Step 6: Combine with Sauce : Pour the hoisin sauce mixture over the turkey and stir well. Let it simmer for 1–2 minutes to thicken and coat evenly.
Step 7: Garnish and Assemble : Stir in chopped green onions, remove from heat, and sprinkle sesame seeds if desired. Spoon the mixture into lettuce leaves, fold like a taco, and enjoy!
