input question: How to chop an onion?

output answer:
First, you need to remove the skin from the onion. Once that is complete, trim off the top, stalky end of the onion with a sharp knife. Cut the onion in half lengthwise. Take one half of the onion and place it flat side down on the cutting board. Make small cuts down the length of the onion, without cutting through to the end. Turn the onion 45 degrees, then make horizontal cuts through the length of the onion. Repeat with the other half of onion. Discard the ends.
