Mmm, some good ideas. I was thinking, maybe something with lemon, or lime, juice might be suitable. I do have a steamer (one of those bamboo ones that goes over a pan).
I'll let you all know when I've had it. Won't be tonight, it'll be frozen. Still, it was a bargain (80p from £1.80) and I got a pot of smoked salmon pate for half price as well, makes the lunchtime celery go down better!
Although the reason I went was, I suddenly fancied sushi for lunch, and I've had a little selection from there before. But either they've disco-ed it, or it's been forced out by the enormous Christmas selection of things-wrapped-in-smoked-salmon. Never mind I treated myself to a chocolate sundae thing instead. And I wonder why the diet doesn't seem to be doing much...
