Thanks everyone, very helpful.
I'd forgotten the whizzed up veg trick Pasta, a woman I worked with used that technique to get veg down her veg phobic children.
I've bought just about every veg in the shop, and found some pork things lurking in the depths of the freezer, so tomorrow morning I'll give this contraption its first go.
I also found a packet of pearl barley at the back of the cupboard so will use that at some point too, good idea Atalanta.
Thanks again for all your input :)
