White bean spinach soup

This is the fastest, easiest soup, and it is SO DELICIOUS.  I had it tonight.  It was finished in less than 30 minutes.  If you have fresh spinach and a few cans of white beans, you have a meal.  I had it with blueberry muffins on the side.  Without the sprinkling of cheese on the top, it is completely vegan!  The creaminess of the soup comes from pureeing some of the white beans and adding them back into the soup.

Italian white bean soup with spinach  (adapted from "Good Housekeeping Vegetarian Meals")

1 TBSP vegetable oil
1 onion, finely chopped
1 stalk celery, finely chopped
1 garlic clove, minced
2 cans cannelini beans or other white beans
2 cups of vegetable broth
1/4 tsp fresh ground pepper
1/8 tsp dried thyme
2 cups of water
10 oz baby spinach (if you use normal spinach, just chop it first)
1 TBSP fresh lemon juice
freshly grated parmesan cheese (optional, but so so good!)

In large saucepan, heal oil over medium heat.  Add onion and celery and cook until tender, stirring occasionally.  Add garlic and cook another minute.  Add beans, broth, pepper, thyme, and water.  Heat to boiling and then reduce heat so that the soup simmers, uncovered for 15 minutes.  With slotted spoon, remove two cups of the bean/vegetable mixture into a separate bowl.  Puree the remaining soup in the saucepan with either an immersion blender or by blending it in parts in a blender or food processor.  Return soup and reserved bean mixture back into the saucepan and heat to boiling, stirring occasionally. Stir in spinach and cook until wilted (about another minute or two).  Stir in lemon juice and remove from heat.  Serve with Parmesan cheese if you choose.
