(Tesco are having an appliance sale - we bought a half price vacuum cleaner and a juicer for a tenner (normally 15 quid).)
This is the juicer I bought.

Anyway, I bought it, and today I made carrot and kiwi smoothies.

I had a large carrot and two kiwis, which I put through the juicer, then added an equal amount of yoghurt and poured it into two mugs and topped up with milk. Very easy, very tasty.
