My wife had trouble on how to dice an onion when we first met, and here is a trick I taught her to make it easier for her to work with onions.

The trick is to leave the root connected.

To dice an onion:

• First cut the onion in half, do not cut off the root.
• Peel off the outer skin.

• Lay the onion on the flat side.
• Cut sections perpendicular to the root.
  • Be sure to NOT cut through the root.

• Now cut perpendicular to your previous cuts.

You now have diced onions.
