Step 1

Preheat oven to broil. Whisk together all ingredients for cajun seasoning. Rub 2 teaspoons of the cajun seasoning into the chicken breasts. Store at room temperature. Cook in a large pan or nonstick skillet over medium heat 4-5 minutes on each side until cooked through.

Step 2

Cut the hoagie rolls lengthwise and place two slices of provolone cheese on each of the "bottom" halves of the rolls. Place them on a baking sheet and cook under the broiler for 2-3 minutes until cheese is melted.

Step 3

While the bottoms of the rolls are broiling and the cheese is melting, whisk together mayo and remaining 2 teaspoons cajun seasoning and spread the sauce onto the top halves of the rolls. When cheese is melted, remove bottom halves from oven.

Step 4

Place chicken breasts on top of the melted cheese and then place jalapeños on top of the chicken. Top each chicken breast with the top half of the hoagie rolls. Serve warm.
