Since starting DD i have started eating more fish. Especially on PP days. I decided to try some fish that I haven't tried before. I bought some smoked haddock, canned mackerel in brine and sardines in brine. In the book it says mackerel and sardines in tomato sauce are ok and it's in the attack section. I just want to make sure its definitely ok to have them in a tomato sauce as I think they would make an easy lunch at work. Things seem to change so often and I don't want to get it wrong.
