Does this mean when I use only half an onion I don!t need to toss the other half. That's what I always do as I only buy those white onions and around here those are at least baseball sized.[/QUOTE] You can chop and freeze the other 1/2 of onion for soups and sauces. At this time of year the prices are coming down on seasonal veg's so I chop up hot peppers-green peppers and onions and freeze them together in small zip bags - ready for a nice big pot of chili. I'm the designated chili chef so when I make a gallon pot this part is done.
