French Onion Soup

My first was at the Captains Quarters with "at at the table prep" caesar salad with Ann C
Was probably 1982. Typically I make my own Caesar as well but decided to make better choices this week as I have been eating badly and there is a reunion coming.
A cold day here in Florida so thought this a good choice

4 servings

4 medium onions sliced thin
4 tbs butter
1 tbs olive oil
1 tsp sugar
3 garlic cloves minced

32 oz beef broth

salt pepper worcestershire to taste

4 slices french bread toasted in 325 oven 30 mins
