No replacement for pasta

Last night I tried out a Hairy Dieters' recipe - developed by Dave Myers and Si King aka 'The Hairy Bikers' - and it was a disaster.  They demonstrated their 'Skinny Beef Lasagne' on TV a while ago and gave it to a group of dieters for their feedback, which produced words such as "delicious, very tasty, gorgeous, amazing" and "you would never know there was no pasta in the lasagne"!  The trick was to replace the pasta with sheets of blanched leeks which, albeit unlikely, having been fooled by the taste team dieters, seemed like a good idea and worth a go.  Do not try this at home.  You will end up with a massive dishful of runny sauce which you can almost pour onto your plate.  When you scoop up some of the sauce you will end up with long slimy strings of leek hanging from your fork.  (Oxford Dictionary definition of "slimy" is "repellently smooth" - what a perfect description.)  I must give it credit, though, for tasting very nice - surprisingly - as long as you didn't look at it on the plate.  But when my husband said that it would go nicely with some pasta, well...
