Season the chicken cubes with garlic and herb seasoning, salt, and pepper. Cook them in olive oil over medium-high heat until golden brown.
Boil salted water and cook the pasta until al dente. Drain well.
Slice off the tops of the kaiser rolls and hollow out the centers.
Combine melted butter with garlic and herb seasoning. Brush this mixture inside and along the edges of each bread bowl.
Bake the brushed bread bowls in an oven preheated to 375°F (190°C) for about 4-5 minutes until lightly toasted.
Mix the cooked chicken with the drained pasta and Alfredo sauce until well combined.
Fill each toasted bread bowl with the creamy chicken Alfredo mixture and top with shredded parmesan cheese.
Return the filled bowls to the oven for another 4-5 minutes until the cheese is melted and bubbly.
Serve immediately while hot, garnished with parsley or red pepper flakes if desired.
