Japanese breadcrumbs make for a crispier coating, but you can always substitute regular breadcrumbs.
Combine 1/2 cup Caesar dressing and next 3 ingredients in a medium bowl. Add chicken; toss to coat. Combine breadcrumbs, flour, and parsley in a shallow dish or pie plate. Dredge chicken in breadcrumb mixture, pressing gently to adhere crumbs to both sides. Place on a baking sheet. Chill 30 minutes.
Heat oil in a large deep-sided skillet 2 to 3 minutes or until hot. Cook chicken, in batches, 3 to 4 minutes on each side or until golden brown. Drain on paper towels. Serve warm or chilled with remaining 1/4 cup Caesar dressing and Romaine leaves.
*For testing purposes, we used Panko Japanese breadcrumbs.
