Prepare the Chicken:
Butterfly the chicken breasts and cut them into thin cutlets.
Season both sides with salt and black pepper.
Lightly dredge in flour, shaking off any excess.
Sear the Chicken:
Heat extra virgin olive oil in a large skillet over medium-high heat.
Cook the chicken cutlets for 3 minutes per side, until golden brown.
Remove from the pan and set aside.
Make the Lemon-Caper Sauce:
In the same pan, sauté garlic for 30 seconds.
Deglaze the pan with white wine or chicken broth, scraping up browned bits.
Stir in lemon juice, capers, and chicken broth; let simmer for 2 minutes.
Swirl in butter until melted and the sauce becomes silky.
Simmer the Chicken in the Sauce:
Return the seared chicken to the skillet.
Spoon the sauce over the top and let it simmer for 4-5 minutes.
Garnish with fresh parsley and serve immediately.
