No more tears
Lots of dishes I cook use chopped onions. The Quickfix book suggests this time-saving trick.
When you are chopping onions, chop up an extra 2 or 3. Freeze 1/2 cup or 1 cup measures in a plastic bag (label!) for quicker week-night prep. You only have to clean the knife and chopping block once, and I also find that the onions cook much quicker after they are frozen. This is one trick I will keep doing!
