Ingredients
1 1/2 pounds boneless, skinless chicken thighs
Kosher salt and freshly ground pepper
Vegetable oil, for grill
Five-Ingredient Barbecue Sauce
4 cups thinly sliced red or green cabbage, or a combination
2 scallions, chopped
1/4 cup mayonnaise
1/2 teaspoon celery seed
1 tablespoon apple-cider vinegar
4 seeded hamburger buns, split
Preparation
Heat a grill to medium-high. Season chicken with salt and pepper. Lightly brush grates with oil. Grill chicken, flipping halfway, until cooked through, about 4 minutes a side. Brush both sides with barbecue sauce and continue cooking, flipping once, until caramelized and lightly charred in places, about 2 minutes more. Transfer to a cutting board and let stand 10 minutes, then coarsely chop.
Combine cabbage, scallions, mayonnaise, celery seed, and vinegar in a bowl. Season to taste and toss to combine.
Grill buns, split-sides down; until lightly golden, about 1 minute. Serve with chopped chicken and drizzle with more barbecue sauce. Top with coleslaw.
