FILL THE CANNELLONI
Preheat the oven to 350°F or 180°C.Arrange your piping bag into a tall container (like a mason jar), folding the top part over the container. With a spatula, fill it with the ricotta filling (you might have to work in batches).Spread a layer of tomato sauce on the bottom of your baking dish.Remove the piping bag from the tall container, twist the empty part to seal it, and grab it tight with your dominant hand.Fillabout20 dried cannelloni tubes from both sides until completely stuffed.Arrange tubes on the baking dish on a single layer.
BAKE
Cover cannelloni tubes with the remaining tomato sauce.Top with 8 ounces mozzarella (chopped) and ½ cup grated parmesan.
