In a small bowl, whisk together the hoisin sauce, soy sauce, rice vinegar, sesame oil, sriracha or chili garlic sauce, brown sugar or honey, and black pepper. Taste and adjust—add more chili sauce for spicier, a little more sugar for sweeter, or a splash more vinegar for brightness. Set aside.
1/4 cup hoisin sauce, 3 tablespoons low-sodium soy sauce, 1 tablespoon rice vinegar, 1 tablespoon sesame oil, 1 teaspoon sriracha or chili garlic sauce, 1 tablespoon brown sugar or honey, 1/4 teaspoon black pepper
Gently separate the lettuce leaves, rinse, and pat dry very well with paper towels so the filling doesn’t slide out. Arrange the leaves on a serving platter. Prepare shredded carrots, sliced cucumber, lime wedges, and any extra sliced green onions and sesame seeds so they are ready for serving.
1 head butter lettuce, 1/2 cup shredded carrots, 1/2 cup thinly sliced cucumber, extra sliced green onions, toasted sesame seeds, lime wedges
Heat the neutral oil in a large nonstick skillet or wok over medium-high heat. Add the ground chicken and cook, breaking it up into small crumbles with a wooden spoon, for 5–7 minutes or until no pink remains and the edges begin to brown slightly.
1 tablespoon neutral oil, 1 1/2 pounds ground chicken
Add the finely diced onion to the pan and cook for 3–4 minutes, stirring occasionally, until softened and translucent. Stir in the garlic, grated ginger, and the white parts of the sliced green onions. Cook for about 1 minute, just until fragrant, without letting the garlic brown.
1 small yellow onion, 3 cloves garlic, 1 tablespoon fresh ginger, 2 green onions
Stir in the chopped water chestnuts and grated carrot (if using). Cook for 2–3 minutes to heat through and let the flavors mingle. The carrot will soften and add a touch of natural sweetness.
8 ounces water chestnuts, 1 small carrot
Pour the prepared sauce over the chicken mixture. Stir well so all of the chicken and vegetables are evenly coated. Cook for 2–3 minutes, letting the sauce bubble and slightly thicken until the filling looks glossy, not watery. If it seems dry, stir in 1–2 tablespoons of water; if it seems too wet, let it simmer for a couple more minutes.
1/4 cup hoisin sauce, 3 tablespoons low-sodium soy sauce, 1 tablespoon rice vinegar, 1 tablespoon sesame oil, 1 teaspoon sriracha or chili garlic sauce, 1 tablespoon brown sugar or honey, 1/4 teaspoon black pepper, 1–2 tablespoons water
Taste the filling and adjust the seasoning as needed—add a pinch of salt, more sriracha, or a squeeze of lime if desired. Stir in most of the green parts of the sliced green onions, reserving a little for garnish.
1 salt, extra sliced green onions, lime wedges
Spoon the hot soy-garlic chicken filling into the lettuce leaves, about 1/4 cup per leaf. Top with shredded carrots, sliced cucumber, extra green onions, toasted sesame seeds, and a small squeeze of lime if you like. Serve immediately while the filling is hot and the lettuce is crisp.
