Begin by seasoning the chicken breasts with salt and pepper.
In a large skillet, heat the olive oil over medium-high heat. Once hot, add the chicken breasts and cook for about 6-7 minutes per side, or until fully cooked through. Remove the chicken from the pan and set aside.
In the same skillet, add the minced garlic and Italian seasoning; sauté for about 30 seconds until fragrant.
Pour in the chicken broth and bring to a simmer, scraping any browned bits from the bottom of the skillet.
Reduce the heat to medium-low and stir in the heavy cream and chopped sun-dried tomatoes, mixing well.
Add the fresh spinach and cook until wilted, about 2 minutes.
While the sauce is simmering, cook the tortellini according to the package instructions. Drain and set aside.
Slice the cooked chicken breasts into strips and return them to the skillet with the cream sauce.
Add the cooked tortellini to the skillet, tossing everything together until well combined. Allow to heat through for a few minutes.
Serve hot, topped with grated Parmesan cheese and garnished with fresh basil leaves.
