Preheat your oven to 220 C (425 F).
Heat a pot of salted water to a boil, then add the pasta and cook that until just tender, drain well (let cool for a few minutes before adding to a Pyrex dish) pour into a 9x13 baking dish.
While the water is heating for the pasta, heat a large non stick pan and add the sausage and break it with a spatula as you cook it, add some chopped up pepperoni slice if want and add to the pan as well, as much as you like. When cooked through, do not drain, just pour into the baking dish and mix with the pasta until "all the pasta is coated with the yummy meatiness." (Author's words, very cool!)
Add the pasta sauce and mix together, now add the pizza cheese blend and mix that in. Once mixed, smooth out the top evenly, top with Mozzarella, then a layer of pepperoni slices.
Bake until bubbly, about 25 to 30 minutes. Remove and let rest for a few minutes, you have a bubbly dish of cheese lava, you are just cooling it a bit before serving.
Serve. Garlic bread would be a great side dish.
