Two meats, two cheeses, and two sauces make this cannelloni doubly good. There's enough in this recipe for a couple of meals too, though I often double it to freeze. I guess it's a real theme with this recipe! In our house it is enjoyed by children and adults alike. You may want to add more pasta sauce, or vary the thickness of the cream sauce - up to your liking. If I can't get nice ground pork at the market, I'll substitute sausages, discarding the casing - a little more flavourful, a little higher fat. It's a real departure for me to not use basil and oregano, but I like the flavour just exactly as is.
