In a large skillet over medium heat, add the ground chicken and sauté for about 7-10 minutes, breaking it apart with a spatula until browned and no longer pink.

Once cooked, reduce heat to low and stir in the Alfredo sauce, mozzarella, and Parmesan cheese. Cook for another 3-5 minutes until cheese melts and mixture is creamy.

Add salt, pepper, and garlic powder to taste, stirring thoroughly to ensure flavor balance.

Preheat the oven to 375°F (190°C) and toast the hamburger buns for about 5-7 minutes until golden brown.

Spoon the Chicken Alfredo mixture onto the bottom half of each toasted bun and top with the other half to assemble the sandwiches.

Serve immediately while warm, optionally with fries or a fresh salad.
