Maybe you can saute the onions first in the soup pot, this way you only use one pot. Maybe you can add to the saute mix some celery and carrots. Good stone soup, lol. :')

My mother used to make this for us with grilled cheese. Thanks for sharing this.

I made a more rich and hearty version. I carmelized an onion and a celery stalk in butter and bacon grease. Then i added at least 5 c. mashed potatoes, a can of cream of mushroom, milk, 2 c. cheddar cheese, pepper, powdered rosemary, thyme, sea salt, and cayenne. I garnished ea. bowl with some chives. Everyone loved it and the best part was it took at the most 10 min. to make!
