Chipotle Sweet Potato Soup

I love sweet potatoes. They are very nutritious (fiber, vitamins A, B6, and C), they are filling, they are versatile, and most importantly, they are delicious. To create this recipe, I used the base of another sweet potato soup that I've been making for a long time. Then I added a twist with chipotle peppers. I served this soup with a side of Spanish rice (Near East is my brand of choice). This soup is quite spicy, which I love, but you can always reduce the quantity of chipotle peppers to tone the spicy factor.

CHIPOTLE SWEET POTATO SOUP
-2 tablespoons olive oil
-2 large sweet potatoes, diced
-1 onion, diced
-1 red bell pepper, diced
-2 carrots, diced
-4 chipotle peppers, seeded and chopped, along with 2 tablespoons adobo sauce (recommended: Goya chipotle peppers in adobo)
-salt and pepper
-pinch nutmeg
-pinch ground ginger
-1 tbsp brown sugar
-5 cups vegetable stock
-scallions, cilantro, or other green garnish

-Heat oil in a large pot, then add onion, red bell pepper, and carrot. Cook about 7-8 minutes, until softened.
-Add salt, pepper, nutmeg, ginger, and chipotle peppers and adobo sauce. Stir and cook about 1 minute.
-Add vegetable stock and sweet potatoes. Bring to a boil, then simmer for about 20 minutes until sweet potatoes are fork tender.
-Remove soup from the heat. Use either an immersion blender or a traditional blender to puree the soup until desired smoothness. *WARNING* If using a traditional blender, be sure to only fill the blender a third of the way and leave the lid cracked to prevent explosions. I am not kidding! Take the time to blend in batches and avoid a catastrophe. Or just get an immersion blender. It's worth the expense if you make a lot of soups and purees.
-Bring soup back up to temperature, and serve, topped with scallions or cilantro.
