I know, it sounds like a really daft question! Can you tell I'm not much of a chef Basically, I want to eat more white fish and the easiest time for me to do this is during the day for lunch (I'm trying to lose some weight, and am particularly trying to eat my biggest meals in the morning and at lunch). But we don't have heating facilities at work. Could you cook white fish and then eat it cold, as you might do with salmon? Or is that idea just totally gross? Any suggestions?
