the only problem with that rocket pesto recipe (which really is scrummy, and so easy) for vegetarians is that it contains anchovies. You'd have to probably increase the amount of fresh grated pecorino or parmesan, and make it a good, aged cheese, to compensate for the intense savoury punch that the anchovies give.

But if they do eat fish, I have another favourite Nigella recipe:

Crab and chilli linguine

I even use tinned white crabmeat and lazy chillis if I'm making this as a quick mid-week supper. It is ridiculously easy and very delicious. You can substitute rocket for the watercress and parsley. Or chuck some fresh basil leaves in. It's the perfect thing for eating in the garden with a glass of wine in the summer.
