Cook the pasta according to package instructions until al dente.
While the pasta cooks, heat olive oil in a large skillet over medium heat.
Season chicken breasts with salt and pepper, then add them to the skillet.
Sauté the chicken for about 6-7 minutes on each side until cooked through. Remove and let rest before slicing.
In the same skillet, add garlic and sun-dried tomatoes, cooking until fragrant.
Stir in chopped spinach, oregano, and basil until the spinach wilts.
Pour in the heavy cream and bring to a gentle simmer.
Add grated Parmesan cheese, stirring until it melts into the sauce.
Combine the cooked pasta and sliced chicken into the sauce, tossing gently to coat.
Taste and adjust seasoning with salt and black pepper before serving.
