The same great combo as buffalo wings (hot sauce, blue cheese, chicken, and celery), but even easier to eat!
Preheat oven to 400°. Arrange rolls, cut-side up, on baking sheet. Bake until golden, about 5 minutes. Spread cut sides with mayo. Sprinkle cheese on roll bottoms. In nonstick skillet, cook chicken, covered, over low, stirring, until heated through, 3 to 4 minutes. Divide chicken among roll bottoms. Drizzle with hot sauce. Top with celery and roll tops.
