01 - Generously coat the steak pieces with salt and freshly ground black pepper.
02 - Warm 1 tablespoon of olive oil in a large skillet over medium-high heat. Arrange the steak in a single layer and sear for 2-3 minutes per side until beautifully browned and cooked to preference. Transfer the steak to a plate and set aside.
03 - Lower the heat to medium. Pour the remaining olive oil and butter into the same skillet. Once the butter has melted, introduce the minced garlic, sautéing for 1 minute until fragrant.
04 - Slowly stream in the heavy cream, bringing it to a gentle simmer. Fold in the Parmesan cheese, stirring continuously for 2 minutes until the sauce is velvety and slightly thickened.
05 - While the sauce simmers, boil the tortellini in a large pot of salted water according to package directions. Drain thoroughly using a colander.
06 - Gently fold the cooked tortellini into the garlic cream sauce until well coated. Return the seared steak bites to the skillet, tossing everything together over low heat for 1-2 minutes to allow the flavors to meld.
07 - Plate immediately, garnishing with fresh chopped parsley and an extra dusting of Parmesan if desired.
