Prep the lettuce and veggies: Gently separate lettuce leaves, rinse, and pat dry. Dice the onion and bell pepper, shred the carrots, and mince the garlic and ginger.
Make the sauce: In a small bowl, whisk soy sauce, rice vinegar, hoisin (or honey), sriracha, and sesame oil.
Taste and adjust heat and sweetness to your liking.
Sauté the aromatics: Heat oil in a large skillet over medium. Add onion and cook 2–3 minutes until softened. Stir in garlic and ginger for 30–60 seconds until fragrant.
Brown the turkey: Add ground turkey.
Cook, breaking it up with a spatula, until no longer pink, about 5–6 minutes. If there’s excess liquid, spoon it off.
Add the veggies: Stir in bell pepper, carrots, and water chestnuts. Cook 3–4 minutes until crisp-tender.
You want them to keep some crunch.
Finish with the sauce: Pour the sauce over the turkey mixture. Stir and simmer 2–3 minutes until slightly reduced and glossy. Remove from heat.
Assemble: Spoon the warm filling into lettuce leaves.
Top with green onions, herbs, sesame seeds, and a squeeze of lime.
Serve immediately: Set out extra sauce and lime wedges. Encourage people to build their own wraps.
