In an extra-large skillet cook beef over medium-high heat until browned. Stir in soy sauce, Asian pepper sauce, and sesame oil. Stir in broccoli slaw. Cook and stir over medium heat 2 to 3 minutes or until slaw mixture is just wilted.
Spoon beef mixture onto lettuce leaves. Top with red sweet pepper and, if desired, peanuts, and/or green onions and additional sriracha sauce. Serve with lime wedges.
