French Onion Soup

Chilly night. French Onion Soup.

Here is my recipe.

3 large sweet onions

Sliced half moon. Sauté with olive oil and herbs de provence I usually slow cook them atleast an hour or so. Until carmalized. Then I add 2 cups of chicken stock and two cups of beef stock. Salt pepper and garlic powder to taste. Cook for 10 minutes. At the last minutes I add a few teaspoons of balsamic vinegar (sherry vinegar is common) but once I only had balsamic and I liked the taste better Then in my oven safe bowl. Toasted bread and good amount of provolone and swiss. Broil until golden and top with chopped parsley
