1 can of low or no sodium Swanson's beef broth
1 medium sized vidalia onion
1 stalk celery.
1 tsp canola or olive oil.
chop onion and celery. Sautee in a medium sized skillet along with the olive oil. Open can of broth, pour into a 1 quart pot, let it start simmering.

My husband says that a good onion soup should cook about 4 hours. Dunno about that, but I think I will start my next batch of soup after breakfast tomorrow. The onions were still a little crunchy.
it is delicious. And it's filling.
And no, it doesn't need cheese. Cheese in soup is icky anyway. I hate cheese snot.
