In a shallow baking dish, whisk breadcrumbs with parmesan, olive oil, and salt. In a separate dish, beat the eggs. Dip chicken first in the beaten egg, then in the breadcrumb mixture and place on the prepared rack. Bake chicken for 10 minutes, then remove and turn on broiler. Top chicken with mozzarella, then return to oven and broil until golden and bubbly, and chicken reaches 165ºF, about 4 minutes more. Serve atop tomato sauce with hot, cooked spaghetti, if desired.
