Follow these detailed steps to create your Creamy Garlic Parmesan Tortellini with Chicken & Broccoli:

1. Cook the Tortellini: Start by boiling a large pot of salted water. Add the cheese tortellini and cook according to package instructions until al dente. Drain and set aside.
2. Sauté the Chicken: In a large skillet, heat olive oil over medium heat. Add the diced chicken breast and season with salt, black pepper, and Italian seasoning. Sauté until the chicken is fully cooked, around 5-7 minutes.
3. Add Garlic: Once the chicken is cooked, add the minced garlic to the skillet. Sauté for another 1-2 minutes until the garlic is fragrant, being careful not to burn it.
4. Incorporate Broccoli: Add broccoli florets to the skillet and stir well. Cook for about 3-4 minutes, allowing the broccoli to soften while still maintaining its vibrant color.
5. Make the Sauce: Pour in the heavy cream and stir to combine. Add the grated Parmesan cheese and continue to stir over low heat until the cheese melts and the sauce is smooth.
6. Combine Ingredients: Gently fold the cooked tortellini into the creamy sauce, ensuring that each piece is coated well. Allow everything to heat through for another 2-3 minutes, stirring occasionally.
7. Taste and Adjust: Taste the dish and adjust seasoning if needed with additional salt and pepper.
8. Serve: Remove from heat and garnish with chopped parsley before serving.
