When I was a personal chef, I cooked for people with all sorts of dietary restrictions.  There was the no gluten family, the vegetarian South Beach dieters and even the bodybuilder who was after as much protein as I could deliver. Balsamic Caramelized Onions

I was happy to whip up all sorts of healthy and creative dishes to meet their needs.  I substituted when I could, or just came up with tasty alternatives.  You don’t eat wheat?  How about my killer rice flour brownies?  Skipping carbs?  Pureed cauliflower it is.  Need more protein?  Frittata for you.

Balsamic Caramelized Onions

I loved the challenge and thought I could handle it all.  That is, until I met one prospective family who had a restriction I just couldn’t meet: no onions!  I told them I just wouldn’t be able to make good-tasting food without onions.  I mean, come on people, there is a reason most diets around the world base their savory dishes on onions.  In Italy they are an integral part of the odori (the mixture of vegetables and herbs that are sauteed in the beginning of most sauces and soups.)  In France they are the base of mirepoix.  In Mexican and Indian cooking, they certainly would be missed.  And so on.  At their simplest, sliced raw they add a firey element to salads and sandwiches.  But cooking them slowly and caramelizing their natural sugars turns them into a thing of beauty.balsamic caramelized onions

Now that they’re in season, I like to celebrate them as the star of the show.  I brought these balsamic caramelized onions to a friend’s house as an appetizer to go with goat cheese.  The hosts were making flatbread pizza in their outdoor pizza oven (so jealous.)  They scattered some of the onions on one of them.  Yum!  They are also perfect for tossing with pasta or mixing with cubes of roasted butternut squash.  The possibilities are endless.
