vegetable broth, water or white wine for deglazing the pan
salt, optional
Instructions
Heat two tablespoons olive oil in a stainless steel or cast iron sauté pan over medium heat. Add the sliced raw onions. I used two large sweet onions.
Stir the onions around in the pan to coat with the oil. Cook over medium heat for about 10 minutes. Revisit the onions about every 10 minutes to make sure they are not burning. Scrape up any of the little brown bits that form on the pan.
Deglaze the pan with a little vegetable broth, white wine or water. Let cool and refrigerate.
