Stracciatelle gets its name from the ragged (stracciata in Italian) appearance of the eggs in this traditional soup. Serve with crostini topped with flaked tuna, endive, scallion, and parsley.
In a large saucepan, bring the stock to a boil over medium-high heat. Reduce heat to low; keep at a gentle simmer.
In a medium bowl, whisk together eggs and parsley. Using a fork, stir stock in a quick circular motion, creating a whirlpool; pour in the egg mixture in a steady stream. Sprinkle in cheese; season with salt and pepper. Ladle into bowls; garnish with parsley and cheese.
