Follow these simple steps to create your Chicken Puttanesca:

1. Heat Olive Oil: In a large skillet over medium heat, add the olive oil and let it heat up.
2. Cook Chicken: Season the chicken breasts with salt and pepper. Place them in the skillet and cook for about 6-7 minutes on each side or until golden brown and cooked through. Remove the chicken and set aside.
3. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 1 minute, until fragrant.
4. Add Tomatoes: Pour in the crushed tomatoes, stirring to combine with the garlic.
5. Incorporate Ingredients: Add the sliced olives, capers, red pepper flakes, and dried oregano. Stir well and let simmer for about 5 minutes.
6. Return Chicken: Nestle the cooked chicken breasts back into the skillet, spooning some sauce over them. Let everything simmer together for another 5-10 minutes to meld the flavors.
7. Adjust Seasoning: Taste the sauce and adjust salt, pepper, or red pepper flakes as desired.
8. Garnish: Remove from heat and sprinkle with fresh parsley before serving.

These steps will lead you to a delicious Chicken Puttanesca that is both satisfying and easy to prepare.
