- 1 cupof onions
Cut the stem end off and cut it in half through the root end. Peal the few outer layers but do not tear them all off. Slice a sliver of one side and stand it up. Make vertical slices evenly spaced apart but do no cut all the way through. Turn the onion back down to its flat side and make another series of vertical slices evenly spaced apart. Give the onion a quarter turn and cut across the vertical slices to complete the dice.
