Colourful mixed peppers and peas tossed with firm-fleshed monkfish, make this fantastically healthy dish a real winner. Serve with ciabatta or focaccia.
Monkfish makes a particularly good choice for a stir-fry because its firm flesh holds its shape well. If unavailable, use skinless, boneless cod or haddock fillet instead. * A pestle and mortar is ideal for crushing the peppercorns, but if you don't have one, put them in the corner of a strong plastic bag and press down with the end of a rolling pin or the back of a wooden spoon.
