How to Make It
Toss together shredded chicken and scallions in a medium bowl. Whisk together mayonnaise, honey, jalapeño, lime zest, lime juice, salt, and pepper in a small bowl. Gently stir mayonnaise mixture into chicken mixture until combined.
Divide chicken mixture evenly among lettuce leaves (about 1⁄2 cup per leaf), and top evenly with mango, cashews, and cilantro leaves. Serve with lime wedges.
