Peel the onion and let’s start to dice and slice!

Now that you have 2 halves of your onion trim both ends and then peel them both. Take one half and place it flat side down on your cutting board so that you have the round part facing upwards.

Now start to slice crossways through the onion slicing off little semi-circular sections as you work your way from right to left (or left to right if you’re left handed like me ;-)).

Make sure you keep the onion tightly together; we don’t want it to fall apart just yet!

Now that you’ve flipped the onion over on its other side start slicing thin slices, about the same thickness as matchstick (but depends how big you want your onion sliced) and continue until you reach the end. Be careful of your fingers as you get towards the end as those onions can get a bit slippery!
