Season steak on both sides and let rest. In a pan, heat olive oil and melt butter on medium heat. Sear steak on both sides and set aside. Add garlic, chicken broth, heavy cream, and Parmesan cheese, stirring constantly. Toss in red pepper flakes, oregano, thyme, and sun-dried tomatoes. Turn down heat to low and stir until thick. Toss in tortellini, mixing until completely incorporated. Cover, stirring occasionally, until pasta is done. Slice up steak, mix into the pasta, or serve on top. Garnish with parsley and more Parmesan cheese.
