Creating Chicken Pizzaiola is straightforward when you follow these simple steps:

1. Prep the Chicken: Start by seasoning both sides of the chicken breasts with salt and pepper.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Sear Chicken: Add the chicken breasts and cook for about 5 minutes on each side until golden brown. Remove the chicken from the skillet and set it aside.
4. Sauté Onions and Garlic: In the same skillet, add the chopped onions and minced garlic. Stir and cook until the onions become translucent, about 3-4 minutes.
5. Add Tomatoes and Seasonings: Pour in the crushed tomatoes, dried oregano, dried basil, and red pepper flakes if using. Mix well and bring to a simmer.
6. Return Chicken to Skillet: Nestle the chicken breasts back into the skillet, ensuring they are covered with the sauce.
7. Simmer: Reduce the heat to low and cover the skillet. Allow the chicken to simmer in the sauce for 20-25 minutes, or until fully cooked.
8. Add Olives: In the last few minutes of cooking, sprinkle the sliced black olives over the chicken.
9. Garnish and Serve: Once cooked, remove the skillet from heat. Garnish with chopped parsley and serve hot.
