Step 1

Prepare outdoor grill for direct grilling over medium-high heat. In small bowl, stir blue cheese, cream cheese and breadcrumbs. Makes about 1 cup.

Step 2

With sharp paring knife, cut each chicken breast horizontally in half, but do not cut all the way through, leaving about ¼-inch uncut. Open chicken breasts; lay flat between plastic wrap on work surface. With flat end of meat mallet, pound each breast to flatten to ¼-inch thickness; remove plastic wrap. Leaving ½-inch border, spoon cheese mixture over bottom halves of chicken breasts, then roll chicken around filling to enclose; secure with toothpicks. Brush with ¼ cup hot sauce; sprinkle with ¼ teaspoon each salt and pepper.

Step 3

Place chicken on hot grill rack; cover and cook chicken 10 minutes.

Step 4

In medium bowl, toss celery, carrots, oil and remaining ¼ teaspoon each salt and pepper; place on hot grill rack and turn chicken. Cover and cook chicken 10 minutes or until internal temperature reaches 165°, and vegetables 5 minutes, turning once.

Step 5

Serve chicken with carrots and celery drizzled with remaining ¼ cup hot sauce sprinkled with additional blue cheese, if desired.
