Buffalo Chicken Sandwiches with Bacon

Directions

1. In a small saucepan over medium heat, bring the first 5 ingredients to a boil; boil, uncovered, for 1 minute. Cool for 10 minutes; set aside 1/2 cup for basting.
2. Flatten chicken to 1/2-in. thickness. Pour remaining marinade into a large shallow container; add chicken and turn to coat. Cover; refrigerate for at least 2 hours.
3. Drain and discard marinade from chicken. Grill chicken, covered, over medium heat or broil 4 in. from heat for 5-6 minutes on each side or until a thermometer reads 170°, basting occasionally with reserved marinade.
4. In a small bowl, combine the blue cheese, buttermilk, mayonnaise, Parmesan cheese, chives, lemon juice, vinegar, garlic and pepper. Spread over roll bottoms; top with the chicken, bacon, cheese, lettuce, tomato and onion. Replace roll tops.
