Creating Tomato Spinach White Wine Chicken is a breeze if you follow these simple steps:

1. Prepare Chicken: Season the chicken breasts with salt, pepper, and oregano on both sides.
2. Heat Olive Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Sear Chicken: Add the chicken breasts to the skillet and cook for about 5-7 minutes on each side, or until golden brown and cooked through. Remove from the skillet and set aside.
4. Sauté Garlic: In the same skillet, add the minced garlic and sauté for about 30 seconds until fragrant.
5. Add Tomatoes: Toss in the halved cherry tomatoes and cook for 2-3 minutes until they start to soften.
6. Pour Wine: Carefully pour in the white wine, scraping up any browned bits from the bottom of the skillet. Allow it to simmer for about 3-5 minutes.
7. Add Spinach: Stir in the fresh spinach and cook until it wilts, about 2-3 minutes.
8. Return Chicken: Place the seared chicken breasts back into the skillet, coating them with the sauce.
9. Simmer: Let everything simmer together for an additional 2-3 minutes to marry the flavors.
10. Garnish: Remove from heat and garnish with fresh basil leaves if desired.
