Preheat the oven to 350°. Grease a star mold with butter. Pour the Giovanni Rana Meat Lovers Sauce in a big bowl and stir. Cook Tortelloni according to package instructions and drain. Add the Tortelloni and the grated Parmigiano Reggiano to the bowl and mix to combine. Add the béchamel sauce and stir very gently. Transfer the pasta to the mold and bake for about 20 minutes until golden and bubbly. Let it rest for 10 minutes out of the oven before unmolding the star and serve.
