From recipe-submitter Stephanie: I have a new and improved version of Easy French Onion Soup: instead of just sauteing Vidalias, use both a red and any sweet onions at the market. Chop and spread out onto a heavy cookie sheet. Toss the onions with olive oil, salt and pepper. Roast in a hot oven (425-450) for about 25-30 minutes. Then simple make the soup as directed. Roasting the onions gives it an additional richness. Yum!
