Step 1: Prepare the Chicken

1. Place the chicken breasts on a cutting board and slice them horizontally into thin cutlets (about 1/2 inch thick).
2. Season both sides of the chicken with salt, pepper, and garlic powder.
3. Lightly dredge the chicken in almond flour, shaking off any excess.

Step 2: Cook the Chicken

1. Heat olive oil in a large skillet over medium-high heat.
2. Add the chicken cutlets and cook for 3-4 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.

Step 3: Make the Sauce

1. In the same skillet, add minced garlic and sauté for 30 seconds until fragrant.
2. Pour in the chicken broth and lemon juice, scraping up any browned bits from the bottom of the pan.
3. Add the capers and let the sauce simmer for 3-4 minutes, or until slightly reduced.
4. Stir in the butter (if using) until melted and combined.

Step 4: Combine Chicken and Sauce

1. Return the chicken to the skillet, coating it with the sauce.
2. Let it simmer for 1-2 minutes to absorb the flavors.

Step 5: Garnish and Serve

1. Sprinkle chopped parsley over the chicken.
2. Garnish with lemon slices for an extra burst of flavor.
