Boil the ravioli according to the package instructions until al dente. Drain and set aside.
Season thinly sliced sirloin steak with salt, pepper, and Italian seasoning.
Heat olive oil in a skillet over medium-high heat. Sear steak slices for 2-3 minutes per side, then remove and set aside.
In the same skillet, melt butter and sauté minced garlic for 1 minute until fragrant.
Add cooked ravioli to the skillet, tossing gently to coat in garlic butter.
Return steak to the skillet, sprinkle with Parmesan, and stir to combine. Cook for 1-2 minutes until heated through.
Garnish with chopped parsley and serve hot.
