Penne with Broccoli and Green Olives (4-6)

Purple Sprouting Broccoli is probably my favourite vegetable and i buy it almost daily from my local greengrocers when it is in season. The best i have ever had came from a stall at Stoke Newington Farmers Market in London, and is definitely one of the things I miss about not living there so far. I have tried to grow it on my allotment but without much success so far. This is from ” River Cafe Cook Book Two”.
