01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Season chicken breast with Cajun seasoning, salt, and pepper. Heat olive oil in a skillet over medium-high heat. Sear chicken for 5-6 minutes per side until cooked through. Transfer to a plate, cool slightly, then dice into small pieces.
03 - In a saucepan, melt butter over medium heat. Add minced garlic and sauté for 1 minute. Add heavy cream and bring to a gentle simmer. Stir in Parmesan, black pepper, and nutmeg if desired, cooking until sauce thickens, 2-3 minutes. Remove from heat and allow to cool.
04 - On a lightly floured surface, roll out the pizza dough into a 12x16-inch rectangle.
05 - Spread Alfredo sauce evenly over the dough, leaving a 1/2-inch border along the edges.
06 - Scatter diced Cajun chicken, mozzarella, provolone, red bell pepper, and green onions evenly over the sauced dough.
07 - Starting from a long side, roll the dough tightly into a log. Pinch the seam firmly to seal.
08 - Using a sharp knife, cut the roll into 12 equal pieces. Arrange each roll, cut side up, on the prepared baking sheet.
09 - Bake for 18-22 minutes, until golden brown and cheese is bubbling.
10 - Remove from oven. Garnish warm rolls with fresh parsley if desired and serve immediately.
