Make Provolone Sauce: Melt butter in a separate saucepan over medium heat. Stir in garlic powder and heavy cream; bring to a simmer. Gradually add provolone and Parmesan cheeses, stirring continuously until the sauce is smooth and creamy. Season with salt and pepper.
Combine & Serve: Return steak to the skillet with vegetables, add cooked tortellini, and pour over the provolone sauce. Mix thoroughly. Garnish with parsley and serve immediately.
