I bought a bag of frozen fish pie mix from Lidl the other - King prawns, mussels, calamari and some sort of fish. I've no intention of making any fish pie, though. What's its really good for is adding to instant noodles - Just put it in the saucepan along with the water and bring it to the boil, give it a couple of minutes, then add the noodles. All the seafoody stuff will be cooked through by the time the noodles are ready.
