Slice each chicken breast horizontally to make thin cutlets.
Set up three shallow bowls: one with flour, one with beaten eggs and water, and one with breadcrumbs mixed with Parmesan.
Season the chicken with salt and pepper.
Dredge each cutlet in flour, dip in egg wash, then coat in breadcrumb-Parmesan mixture.
Heat olive oil in a large skillet over medium heat.
Cook cutlets 3–4 minutes per side or until golden brown and cooked through.
Drain on paper towels and serve hot with lemon wedges.
