To make the marinara sauce- In a food processor combine stewed tomatoes, tomato paste, parsley, garlic, oregano, salt, and pepper. Blend until smooth. In a large skillet over medium heat add olive oil. Add onion and sauté for 2 minutes. Add the blended tomato sauce and the white wine. Simmer for 30 minutes, stirring occasionally.
While marinara sauce is simmering pre-heat the oven to 350 degrees. Place chicken breasts between 2 sheets of wax paper and pound until they are about a ½ inch in thickness. In a pie plate combine bread crumbs and parmesan cheese. In a bowl beat the eggs together. In a separate pie plate add the flour. Dredge chicken breasts first in the flour, then in the egg and then in the breadcrumb mixture.
Heat about a ½ inch of oil in a large skillet over medium-high heat. Add chicken breasts and sauté until browned on both sides (cook until only browned, do not cook all the way through). Place chicken breasts onto a lightly greased oven safe baking dish. Spread a thin layer of that marinara sauce over each chicken breast (continue simmer marinara sauce). Place into the oven and bake at 350 degrees for 25 minutes or until the chicken is fully cooked (the internal temperature has reached 165 degrees). During the last few minutes of cooking top each chicken breast with shredded mozzarella cheese.
While the chicken is in the oven, cook linguini according to package directions. Once the chicken is done baking, serve with linguini and leftover marinara sauce.
