01 - Bring a large pot of salted water to a boil. Cook cheese tortellini as directed on the package, adding broccoli florets for the final 2 minutes of cooking. Drain well and set aside.
02 - Season chicken pieces with salt and black pepper.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken and sauté until golden and thoroughly cooked, about 5 to 6 minutes. Transfer chicken to a plate and set aside.
04 - In the same skillet, melt unsalted butter. Sauté minced garlic for 1 minute until fragrant.
05 - Reduce heat to medium and pour in heavy cream. Stir to combine and simmer gently. Add grated Parmesan cheese and stir continuously until the cheese melts and sauce thickens, about 2 to 3 minutes.
06 - Return cooked tortellini, broccoli, and chicken to the skillet. Toss until evenly coated with the cream sauce. Add crushed red pepper flakes if desired.
07 - Taste and adjust with additional salt and black pepper as needed.
08 - Serve immediately, garnished with extra Parmesan and fresh parsley if desired.
