Preheat oven to 425 degrees. Line a baking pan with foil and set aside.

In a shallow pan on plate, mix breadcrumbs, cheese (reserve 1 T for garnish), Italian seasoning, and ½ t. salt.

In a separate dish, whisk egg with a tablespoon of water and ¼ t. salt to create an egg wash.

Dip chicken tenderloins in egg wash, then dredge in breadcrumb mixture. You may need to gently press crumbs onto the chicken to get them to stick.

Spray the foil covered baking pan with cooking spray.  Place prepared chicken tenderloins on pan. Spray lightly with cooking spray before placing in the preheated oven.

Cook prepared tenderloins for 20 minutes total, removing pan after first ten minutes and flipping chicken to other side.

While the chicken is cooking, fill a pot with salted water and place on stove at high heat.  When water is boiling, cook spaghetti according to package instructions.  At the same time, in a separate pan, heat the tomato sauce.

When pasta is cooked, divide onto plates. Pour sauce over the pasta, top with chicken parmesan tenderloins, and sprinkle a little of the reserved cheese on top.

Serve immediately.
