How to Make It
Pierce each squash with a fork. Microwave at high for 20 minutes or until tender, and cool. Cut each squash in half lengthwise, discarding the seeds and membrane. Remove the pulp.
Heat the olive oil in a Dutch oven over medium heat. Add the onion, and cook for 5 minutes or until golden. Place the onion, squash, and gingers in a blender, and process until smooth. Return the squash mixture to the pan. Stir in the vegetable broth, and cook for 5 minutes or until thoroughly heated. Spoon 1 1/2 cups soup into each of 4 individual soup bowls. Top each serving with 1 tablespoon green onions, 1 teaspoon chopped peanuts, and 1 teaspoon sour cream.
