In a large skillet, heat the olive oil over medium heat. Once hot, add the diced chicken and season with salt, pepper, and Italian seasoning. Cook until the chicken is browned and cooked through, about 6-7 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for about 30 seconds or until fragrant, being careful not to burn it.
Add the cherry tomatoes to the skillet and cook for 3-4 minutes until they start to soften.
Pour in the chicken broth and bring to a simmer. Add the heavy cream and stir to combine, letting it simmer for 2-3 minutes until it thickens slightly.
Toss in the spinach and cooked chicken, allowing the spinach to wilt for about 1-2 minutes.
Meanwhile, cook the tortellini according to package instructions; drain and set aside.
Add the cooked tortellini to the skillet, gently stirring to coat everything in the creamy sauce. Adjust seasoning with more salt and pepper if needed.
Serve hot, garnished with fresh basil leaves and a sprinkle of grated Parmesan cheese on top.
Notes
Feel free to use different types of tortellini or add more vegetables.
