I have to eat cheese every day at work to make sure it's up to standard - therefore, cheese isn't a treat to me anymore. (I look so elegant using a spit pot). xx
I think 28g is enough for me...i grate it using the fine side of the greater and get plenty enough for a sarnie, jacket spud etc.
I love the fact you can have any cheese on SW when i did WW i was fed up to the back teeth of that horrid rubbery cheese!
