Season chicken with salt and pepper. In a large skillet, heat olive oil over medium heat. Sear chicken until golden and cooked through (6–7 minutes per side). Remove and set aside.

In the same skillet, sauté garlic for 1 minute. Add cherry and sun-dried tomatoes, cooking for 2–3 minutes.

Stir in spinach until wilted. Pour in cream, Parmesan, and Italian seasoning. Simmer until the sauce thickens slightly.

Return chicken to the pan and spoon sauce over the top. Simmer for 2–3 minutes more.

Serve hot with pasta, mashed potatoes, or crusty bread.
