Trim the leek, wash it well and mince, to make about 1 cup. In a saucepan, bring the leeks, milk, pepper, and salt to a boil. Simmer for 2 minutes and then stir in the oats. Cook for about 2 minutes. Serve immediately, or keep warm in a double boiler over warm water. If the soup thickens too much, thin with milk or water.
