Season the chicken breasts with salt and pepper.
In a large skillet, heat the olive oil over medium-high heat.
Add the chicken breasts to the skillet and cook for 6-7 minutes on each side until golden brown and cooked through.
Remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the minced garlic and sun-dried tomatoes, sautéing for about 1-2 minutes until fragrant.
Pour in the heavy cream and stir to combine everything well.
Sprinkle in the Italian seasoning and add the fresh spinach. Stir until the spinach wilts.
Return the chicken to the skillet, coating it in the sauce. Let it simmer for 2-3 minutes to absorb flavors.
Taste the sauce and adjust seasoning if necessary before serving with grated Parmesan cheese.
