Green Soup with Yam and Sage

I spent a really large chunk of today making this soup. Of course, by "really large," I mean a couple hours. Kayla was at work, and the quantity of chopping for this recipe was more extensive than previously acknowledged. However, I REALLY like it. Although, I am quite partial to this sort of soup. It is very smooth, and light. It makes A LOT of soup, however, it is quite low in calories, so you can eat a lot. Not to mention, keep it in the fridge.

Enjoy!

Makes: 8 servings (1.5 cups each)
Calories per serving: 125
Time: 2 hours total
Ingredients:  
  3 Tbs EVOO
  2 large onions, chopped

  1 tsp salt

  4 cups water

  4 sliced garlic cloves

  1/2 tsp thyme

  1 large bunch of kale

  2 medium sweet potatoes (about 1.25lbs)

  12oz spinach

  1 tsp sage

  4 cups vegetable broth

  1 Tbs lemon juice

Directions:

1) Heat Tbs EVOO in large skillet over high heat. Add onions and 1.4tsp salt; cook, stirring frequently for 5 minutes. Reduce heat to low and stir in 2 Tbs water, garlic, thyme, and cover. Cook, stirring frequently until the pan cols down, then occasionally (always recovering pan) until they have a deep caramel color (about 30 minutes).

2) Meanwhile, remove stems and ribs from Kale and stems from spinach. Chop kale and spinach (do not combine them!). Peel and dice potatoes into 1-inch pieces. Put the spinach aside.

3) Add 4 cups water and some salt into a big soup pot. Add kale, potato, and sage. Bring to boil. Reduce heat to summer, cover and cook for 15 minutes.

4) Stir in spinach, return to a simmer and cover and cook for 10 minutes (stirring once in the middle). When the onions are caramelized, stir a little of the simmering soup liquid into them. Add them to the soup. Add broth to the soup. Return to a simmer, cover, and cook for additional 5 minutes.

5) Puree the soup with a blender in batches (blends really easily, don't worry!). Return blended mixture back to pot, and add cayenne, some pepper, and the lemon juice. If it is too sweet, add more lemon juice. Basically add anything you'd like to taste!
