Season chicken cubes with garlic and herb seasoning, salt, and pepper. Heat olive oil in a large skillet over medium-high heat. Cook chicken for 6–8 minutes until golden and fully cooked.
Bring a pot of salted water to a boil. Cook pasta according to package directions until al dente. Drain and set aside.
Cut the tops off the kaiser rolls and hollow out the centers with a spoon to create bowl shapes. Be careful not to tear the bottoms.
Mix garlic and herb seasoning into melted butter. Brush the inside and edges of each bread bowl with the garlic butter.
Place bread bowls on a baking sheet. Bake at 375°F for 4–5 minutes until lightly toasted.
Lower heat to medium. Add cooked pasta and Alfredo sauce to the skillet with chicken. Stir until everything is evenly coated and heated through.
Spoon the chicken Alfredo mixture into the bread bowls, filling them to the top. Sprinkle Parmesan cheese on top.
Return the filled bowls to the oven and bake for another 4–5 minutes until the cheese is melted and the bread is golden on the edges.
