Start by cutting the chicken breasts into bite-sized pieces.
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the chicken pieces along with the herb and garlic seasoning. Sauté for about 5-7 minutes, or until the chicken is browned and cooked through.
Once the chicken is cooked, add the campanelle pasta, spaghetti sauce, water, and red pepper flakes to the pot. Stir everything together.
Bring the mixture to a boil, then reduce the heat to low. Cover the pot and let it simmer for about 12-15 minutes, or until the pasta is tender.
While the pasta is cooking, combine the panko bread crumbs, melted butter, garlic powder, and half of the grated parmesan in a small bowl. Mix well.
Once the pasta is cooked, remove the pot from the heat. Stir in the shredded mozzarella and the remaining parmesan cheese. Sprinkle the panko mixture evenly over the top.
If your pot is oven-safe, place it under the broiler for 2-3 minutes, or until the topping is golden and crispy.
Remove the pot from the oven and let it rest for a few minutes. Serve warm, garnished with additional parmesan if desired.
