2 tablespoons olive oil
1 large onion, diced
2 medium potatoes, sliced
4 cups raw radish greens
4 cups water or soup stock
optional, to make the soup creamy: 1 can white beans, or 1 cup cream
salt and pepper to taste
1 radish, sliced
Melt oil in a large saucepan over medium heat. Stir in the onion, and
sauté until tender. Mix in the potatoes and radish greens, coating
them with oil. Pour in stock, and bring the mixture to a boil. Reduce
heat, add optional beans or cream, and simmer 30 minutes. Allow the
soup mixture to cool slightly, and transfer to a blender. Blend until
smooth. Return the mixture to the saucepan. Add salt and pepper to
taste. Cook and stir until well blended. Serve with radish slices.
