Curried Sweet Potato, Carrot, and Red Lentil Soup
Recipe from Spilling the Beans
Serves 6

Canola or olive oil
1 Onion, chopped
1-2 Garlic cloves, crushed
1 Tbsp grated fresh ginger
1/2 Cup dry red lentils
1 Medium sweet potato, peeled and cut into chunks]
1 Carrot, peeled and chopped
2 tsp curry paste or powder
4 Cups chicken or vegetable stock
Salt to taste
1/2 to 1 Cup half and half (optional)
Plain yogurt or sour cream, for serving (optional)
Cilantro, chopped, for serving (optional)

In a large saucepan, heat a drizzle of oil over medium high heat.  Saute the onion, garlic, and ginger for about 5 minutes, until the onion is soft.  Add the lentils, sweet potato, carrot, curry paste, stock and salt, along with a cup of water.  Bring to a boil, then turn the heat down, cover and simmer for 30 minutes or so until the vegetables are very tender.  Add the cream, if you are using it, and use a handheld immersion blender to puree the soup right in the pot.  Taste and adjust seasonings if needed.  Serve immediately or cool and refrigerate to reheat when you want it.  Serve hot, with a dollop of yogurt or sour cream and cilantro, if you like.
