Heat the heavy cream in the microwave until it is hot.
Whisk together the olive oil, hot cream, and melted butter. Add the wine, garlic powder, onion powder, and parmesan. Stir well until the parmesan has melted. It is okay if it doesn't melt all the way.
Place the fresh, refrigerated ravioli into a grill-safe baking dish. Pour the sauce on top and then top with the shredded mozzarella.
Place the dish into the Traeger.
Let bake for 20-30 minutes, or until the ravioli is tender and the sauce is good and bubbly.
