Creating Tomato Basil Chicken is straightforward when you follow these easy steps:

1. Prepare Chicken: Start by seasoning the chicken breasts with salt, pepper, and oregano.
2. Heat Oil: In a large skillet, heat the olive oil over medium heat.
3. Cook Chicken: Add the chicken breasts to the skillet. Cook for about 5-7 minutes on each side, or until they are cooked through and browned.
4. Add Garlic: Once the chicken is cooked, remove it from the skillet and set it aside. In the same skillet, add minced garlic. Sauté for about 30 seconds until fragrant.
5. Combine Tomatoes: Add the halved cherry tomatoes to the pan. Cook for 3-4 minutes, allowing them to soften and release their juices.
6. Incorporate Chicken: Return the chicken to the skillet with the tomatoes. Stir in the chopped basil and cook for an additional 2-3 minutes.
7. Finish Off: Taste and adjust seasoning if needed. You can add grated Parmesan cheese at this stage if desired.
8. Serve: Plate the chicken and tomato mixture, garnishing with additional basil and lemon wedges for a fresh finish.

These steps encapsulate the essence of preparing Tomato Basil Chicken with little fuss and lots of flavor.
