Pound chicken breasts to an even thickness of about 1/2 inch.
Set up three shallow dishes: one with flour mixed with salt, pepper, and garlic powder; one with beaten eggs; and the last with Parmesan and breadcrumbs.
Dredge each chicken breast in flour, dip in eggs, and coat evenly with the cheese-breadcrumb mixture.
Heat olive oil in a skillet over medium heat and cook the breaded chicken for about 5-7 minutes on each side until golden brown and cooked through (internal temperature should reach 165°F).
In the same skillet, add chicken broth and lemon juice, simmering briefly to create the sauce.
