Heat 1/2 teaspoon oil in a small saucepan over medium heat. Add garlic; sauté 30 to 45 seconds or until tender. Add canned tomatoes, 1 tablespoon basil, 1 tablespoon parsley, vinegar, tomato paste, sugar, and 1/8 teaspoon salt. Bring to a boil; reduce heat, and simmer, uncovered, 15 minutes.
Combine breadcrumbs, 1 tablespoon Parmesan cheese, 1 tablespoon basil, 1 tablespoon parsley, 1/8 teaspoon salt, and 1/4 teaspoon pepper in a shallow dish. Dredge 1 turkey cutlet in flour. Dip in egg white; dredge in breadcrumb mixture. Repeat procedure with remaining cutlets.
Heat 2 teaspoons oil in a nonstick skillet over medium-high heat. Add turkey; cook 4 to 5 minutes on each side or until cutlets are done. Leave turkey in pan and spoon 1/4 cup tomato sauce on top of each turkey cutlet. Sprinkle mozzarella and 1 tablespoon Parmesan cheese evenly over tops of cutlets. Remove pan from heat. Cover and let stand until cheese melts. Garnish with parsley, if desired.
