Add the tomato sauce
, capers, and olives. Close the lid
Cook on low for 4 hours, or high for 2
Approximately an hour before serving, spiralize the zucchini
Salt the zucchini noodles over a colander and mix them up. Let them rest for 10 – 15 minutes to release their liquid.
Using a clean tea towel, line it with kitchen towel and lay the zoodles onto the paper. Gently blot the extra moisture off them. Get them as dry as possible.
Put them in a bowl and heat them in the microwave for 3 – 4 minutes on high. You don’t want to cook them too long as they will get mushy.
Serve them onto plates, and add the sausage puttanesca sauce on top. Garnish with parmesan cheese.
