Roast Red Pepper Shells With Black Olives and Parsley

Serves: 4
Takes: 30 mins

This luscious pasta dish is one of my favourites. Roasting the red peppers in the oven gives the sauce a lovely smoky and rich flavour, which is balanced perfectly by the tart black olives.

When To Eat

I recommend eating this dish from May till October. British capsicum peppers are in season during these months and have a beautifully fresh sweet flavour.
