When using for the Orzo Bolognese, make sure the sauce is at room temperature or even slightly warmed in a sauce pan on the back burner. You will need 1 2/3 cups for the Orzo Bolognese. Yes, of course you can use more if so desired!
Sprinkle the cheese on top, fold some in, leaving most to puddle in spots so that it will melt beautifully in the oven.
Bake in the centre of the oven for 20 minutes, or until it is heated through. If the cheese hasn't browned to your liking, feel free to place the baking dish under the broiler till desired burnish is achieved, keep your eye on it! Sprinkle more parmesan cheese on top.
I say that this feeds 4 comfortably. But if you have hungry men, just add more of the bolognese!
