Heat your oven to 400°F (if you have a ventilated oven, do NOT use this option)
If you are lucky enough to live near a pizzeria that will sell you some dough, buy enough for a couple of pizzas. Or you can purchase par-baked or frozen pizza shells.... or you can make a batch of pizza dough!
Clean and cook your greens. If you can't find broccoli di rape, spinach is a delicious substitute! Swiss chard would also work well.
When it is cooked, drain very well and chop it coarsely; sauté a couple of garlic cloves in some olive oil. Add the greens and let them cook a few minutes to absorb the flavour of the garlic and to allow the liquid to evaporate.
In the meantime, take the sausage out of its casing (I used 2 sausages and about 2 cups of cooked greens) and fry it slowly in a frying pan. When the fat is rendered, pour it off. Now mix the sausage in with the greens.
Oil your pizza pans or cookie sheets and prepare your pizza, calzone or both like I did. I made 1 pizza and 1 calzone.
Put the pizza and/or calzone into the hot oven. Place one pan on a rack very close to the bottom and the other on the middle rack. After about 10 minutes, switch pans and cook another 5 minutes or until done.
