Mandolin

I have a mandolin, not the musical sort, but the 'cut the tips of your fingers off if you aren't careful' sort. It's a fantastic little gadget, it cuts spuds finely if I want to  make Dauphinoise potatoes. It also slices onions finely for when my L&M wants a cheese & onion toastie. When I make him a toastie I slice a whole onion, use what I need for him & then the rest goes in a plastic tub in the fridge to be used up later in the week. No more half onions drying out & forgotten in the back of the fridge.
