In a shallow pan (such as a pie plate or baking dish), mix flour, salt, pepper, Italian seasoning and garlic powder. Rinse chicken and pat it dry. Dredge the chicken through the flour mixture to coat it completely.
Mix together Parmesan cheese, Panko breadcrumbs and 1 teaspoon Italian Seasoning and set aside.
Heat a 12" heavy bottomed skillet over medium heat. Add ¼ cup of canola oil. When the oil is hot, add the chicken tenders and fry until golden brown and crispy; about 3 minutes per side. Transfer chicken to a paper towel lined plate. (see notes below if you prefer not to fry the chicken).
Wipe out the skillet with a paper towel and add 2 tablespoons of oil. Saute diced onions until translucent, then add minced garlic, pasta, chicken stock, pasta sauce and salt and pepper to taste. Bring to a boil, cover and simmer for just about 15 minutes, or until the pasta is al dente (there will still be a little liquid in the pan). Stir in 1 cup of Mozzarella cheese until melted.
Nestle the chicken tenders into the pasta and top with remaining Mozzarella and the Parmesan/breadcrumb mixture. Place the skillet under the broiler for about 5 minutes, or until cheeses are melted and breadcrumbs are golden brown.
Serve immediately.
Notes
If you prefer to not fry the chicken, do this in place of steps 1 and 3.Dice 2 chicken breasts into equal sized, one-inch pieces. Season with salt and pepper. Heat 2 tablespoons canola oil in a 12" inch skillet over medium heat. Add onions and cook until translucent; add chicken pieces and cook sear (cook just until browned but not cooked through). Continue with step 4.
