I'm a big fan of beet soup. It always seems to come out yummy even when I change up the ingredients.
Saute peeled and chopped onions, garlic, carrots and celery in butter.
Add a quart or two of chicken stock.
Add peeled and chopped beets and lots of potatoes.
Boil it all until the potatoes and beets are soft enough to puree in a blender.
Make the puree (leaving some of the beets and potatoes in the soup) then stir it back into the soup.
Add a tablespoon or so of vinegar or lemon juice for a very tiny little kick.
Add lots of dill weed, salt, pepper and any other herbs that sound good at the time.
Simmer 'till you can't wait any longer to eat.
