I've got quite a small kitchen and would love a halogen oven, but haven't the space so my best gadgets are; my Bamix, which does most of the jobs a full size food processr does and my knife sharpener, which suckers to the work top. I "touch up" my knives frequently and the local butcher re-ground my 9 inch chefs knife for me, so just a light touch is all. I also have a Grater from the CBeebies "I can Cook" range, which I bought for my grand daughter to use and is absolutely superb. No danger of skinning fingers. It works like a Mouli , but is suckered to the table and you just wind the handle. It catches the grated food too in a jug.
I also love my stainless steel cooking pot , which cost about £10 at LIDL and is used absolutely EVERY day usually with a steamer sat on top for veggies. I have other pans, but this one always comes out first
then there's the slow cooker, the wok, the combi micro-wave... Oh Dear! I do cook a LOT
