Here is one I make, I use either sweet potatoes or butternut squash.

Ingredients:

1/4 cup olive oil
2 large onions, sliced thin
4 garlic cloves, minced
6 cups of chicken stock
1 1/2 cups chopped fresh (or canned) tomatoes
2 large sweet potatoes, peeled and cut in 1 inch pieces
(**or you can use a butternut squash)
2 carrots, sliced thin
2 Tbsp. dried parsley
1 1/2 tsp. salt
Pinch of cayenne pepper
Fresh ground pepper
5 cups fresh spinach

Heat the olive oil in a large pot over medium heat. Add the onions and garlic and cook about 10 minutes. Stir in the rest of the ingredients except the spinach.

Bring soup to a boil, cover and reduce heat. Cook about 40 minutes or until the sweet potatoes are tender. Remove 2 cups of soup and puree it in blender, then return to pot.

Stir in the spinach and cook another 5 minutes.

....I have a pic of the soup on my blog, if you are interested.

This is called pumpkin soup...but works equally well with butternut squash...perhaps even better...and it also is good with sweet potato.
But pumpkin comes in a can....and is an easy way to make it.
