1. Prepare the Chicken: In a shallow dish, combine the flour, Parmesan cheese, oregano, salt, and pepper. Dredge the chicken slices in the seasoned flour, shaking off any excess.
2. Brown the Chicken: Heat the olive oil and butter in a large skillet over medium heat. Brown the chicken slices on both sides, about 2-3 minutes per side.
3. Make the Lemon Sauce: Add the chicken broth and white wine (if using) to the skillet. Bring to a boil, then reduce heat and simmer for 5 minutes, or until the sauce has reduced by half.
4. Add the Lemon Juice and Capers: Stir in the lemon juice and capers. Cook for an additional 2-3 minutes, or until the sauce has thickened.
5. Serve and Garnish: Transfer the chicken and sauce to a serving dish. Garnish with fresh parsley and serve immediately
