In a separate shallow bowl, combine 1/2 cup flour, 2 Tablespoons grated parmesan, 1/2 teaspoon salt and 1/4 teaspoon pepper.
Heat 1/4 cup olive oil in large skillet over medium heat.
Dip each chicken cutlet into beaten eggs, then coat in the flour mixture. Place in the pan with heated oil.
Cook chicken 3 minutes per side, until light golden brown, then remove to a plate and tent with aluminum foil.
Add lemon slices to the pan and cook until browned on both sides. Remove from pan and set aside.
To the same pan, add 1 cup chicken broth, 3/4 cup white wine, and 2 Tablespoons lemon juice. Bring to a simmer; simmer 4-5 minutes or until slightly reduced.
Combine butter and flour. Add to the sauce, whisking constantly.
Add the chicken and lemon slices back to the pan. Cook over medium-low heat until heated through, about 5 minutes.
Spoon the sauce over the chicken. Garnish with parsley and season with additional salt & pepper as desired.
