Sausage, Greens and Semolina Pizza

2 leeks
3 cloves garlic
2 bunches greens (mustard, chard, kales)
4 sausages (sweet Italian, spicy or hot)
6 to 7 tbsp olive oil
Semolina linguine for 4
salt and pepper
Pitted black olives
Crushed red pepper flakes
Parmesan

Wash and thinly slice the leels, peel and chop the garlic. Remove any large stems from the greens, cut the leaves crosswise into a chiffonade, and wash and dry them. Slice the sausages. Cook the leeks, garlic and sausage in about 5 tablespoons olive oil for 10 minutes or so. Add the greens and continue cooking for 5 minutes or more, until they are soft and wilted. The addition of a little water or stock wil lhelp to steam them. Moisten the misture with another tablespoon or two of olive oil. Cook the pasta and add it to the pan. Toss all together and taste for seasoning. Serve garnished with a generous spinkling of pitted black olives and a litttle crushed red pepper if you like it spicy. Serve with freshly grated parmesan cheese at the table.
