01 - Place chicken breasts between two sheets of plastic wrap and pound to an even 1/2-inch thickness using a meat mallet. Season both sides with salt and freshly ground black pepper.
02 - Arrange three shallow bowls: place flour in the first, beat eggs with milk in the second, and combine grated Romano cheese, plain breadcrumbs, and chopped parsley in the third.
03 - Dredge each chicken breast in flour, shaking off any excess. Dip into the egg mixture, then firmly press into the Romano-breadcrumb mixture to ensure a thorough coating.
04 - Heat olive oil and unsalted butter in a large skillet over medium heat. When hot, add the breaded chicken cutlets in batches as needed. Cook 3 to 4 minutes per side, or until golden brown and the internal temperature reaches 165°F. Transfer cooked cutlets to a plate lined with paper towels.
05 - Arrange cutlets on serving plates. Garnish with extra chopped parsley and serve immediately with lemon wedges.
