I picked up a Tesco magazine today - alongside the usual patronising drivel about "mums", there's a promotion page about "tuna fillers" (which look as nice as they sound). I quote:
"Mum's lunch. Watching your weight? Mix reduced fat Tuna & Sweetcorn Filler (35 per cent lower in fat than the standard range) into a Greek potato salad.
Dad's lunch. For a hearty, fuss-free meal, fill a jacket potato with Tuna&Sweetcorn Filler, top with grated cheese and grill for a moment to melt the cheese. Guaranteed to beat boardroom boredom."
For the record, in my house, it's DH who's counting calories and me who's eating for Britain, as I'm breastfeeding (but to be honest I eat like that all the time anyway).
