Roast cod with tomato vinaigrette
The vinaigrette is made in advance as can the beans and potatoes

This is one of my go-to recipes, ideal for dinner parties, but I am just as likely to make it for one or two people. The vinaigrette is made in advance and both the beans and potatoes that go with it can be pre-cooked and then revitalised in boiling water while the fish is roasted.
