I think the onion is taken for granted and unfairly maligned. Scott Conant of TV Network's "Chopped" will whine for hours if there is a raw onion anywhere near his food. People will avoid onions because of "onion breath." Onions are never the featured player in a recipe, unless it's French onion soup.
I love onions. I always have. When I was a kid, my dad would make onion sandwiches. Bread, butter, onion, salt, pepper and maybe some sharp cheddar cheese and German mustard. I still eat them, but only when I'm alone. We also used to eat green garden onions as a snack vegetable, just like a carrot or celery.
I think it's time that we appreciate all the onion has to offer. One cup of onion has 2 grams of protein and 3 grams of fiber and only 64 calories. That's about 10% of your daily fiber needs. Adding a cup of chopped onions to a recipe is a simple way to increase healthfulness of that dish. Onions are really low on the glycemic index and fight inflammation. They're a good source of Vitamin B6, Folate, Potassium and Manganese, and Vitamin C. They may also help prevent neck and head cancers. Red onions may improve cholesterol.
