I'm with you, Kirsty, sushi is one of my standard low-point, "virtuous" lunches. Either veggie or fish. A normal lunch pack from Marks & Spencers is 5pts, I think. Mary, have you worked out the points on the sushi? Does it come ready-packed or do you mainly eat it in restaurants?
It sounds like it's totally a trigger food, and I do sympathise - I'm that way about peanut butter. Can't have it in the house because once I start eating it I can't stop. And Blokey's the same, so between us we would decimate world peanut butter stocks if we were left to it
But I do have it at other people's houses where eating it with a spoon would just be plain rude
Like Kirsty says, don't deprive yourself totally - you can work it in!
