i simmered a load of veg yesterday, removed half from the pan and used a hand whizzer to whizz up the half left in the pan till it was thick and smooth. i then put back the unliquidised half into the pan and re-heated the whole lot. we had that with wholemeal pasta for our evening meal - perfect home-made vegetable pasta sauce, very healthy, very cheap, very tasty and very nourishing.
i would recommend anyone to get a hand-held blender, very quick and easy to use and far less washing up than a traditional liquidiser/blender, not to mention cheaper.
