This comes from Paleomg.com and is titled Crock Pot Sweet Potato Basil Soup. I took the advice of someone who had previously made this little gem and added sweet curry powder and cumin rather than basil.
2 sweet potatoes or yams, diced
½ yellow onion, sliced
1 (14oz) can of coconut milk
1 cup vegetable broth
2 garlic cloves, minced
1 Tbl dried basil
salt and pepper, to taste
Place all ingredients in the crock pot and stir to mix. Cook for 3 hours on high. Use a hand blender, blender or food processor and puree the mixture until smooth. Serves 3-4.
