Whisk the wing sauce with the butter; set aside. Stir the mayonnaise with the sour cream, blue cheese and green onion; set aside.

Prepare the chicken burgers according to package directions. Brush the burgers with the wing sauce mixture during the last 5 minutes of cooking.

Layer lettuce, tomato, burger and blue cheese dressing on buns.

Tip: For a less spicy burger, use half barbecue sauce and half hot sauce instead of the Buffalo wing sauce.

Substitute Louisiana-style hot sauce if you don't have Buffalo wing sauce.

For a smoky flavor, add bacon to your burger.
