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

1. Heat Oil: In a large skillet, heat the olive oil over medium heat.
2. Cook Chicken: Add the chicken breasts to the skillet. Cook for about 5-6 minutes on each side until browned. Remove them from the skillet and set aside.
3. Sauté Vegetables: In the same skillet, add the sliced onion and bell pepper. Sauté until softened, about 3-4 minutes. Add the minced garlic and continue for another minute.
4. Add Tomatoes and Spices: Pour in the diced tomatoes, oregano, basil, salt, and black pepper. Stir to combine.
5. Return Chicken: Place the chicken breasts back into the skillet. Spoon some of the sauce over the chicken.
6. Simmer: Reduce the heat to low. Cover and simmer for 20 minutes, or until the chicken is cooked through.
7. Serve: Once cooked, remove from heat and sprinkle with fresh parsley. If desired, top with grated Parmesan cheese.

With these steps, you’ll effortlessly prepare a dish that fills your home with aromatic scents and delights the palate.
