Think of them as a mini, high temperature, oven. They are great for cooking stuff from frozen (fish, pies, chips especially, mini pizzas) sausages are brilliant, 'roasted' veg, chicken pieces, bacon, (make a foil tray for them to sit in), anything small you would put in an oven really. One of my daughters does a full cooked breakfast for herself in it....the more you use it the more you will think of. The title of fryer is misleading because there is virtually no fat involved. They are also really quick.
