In a medium bowl, whisk together the eggs, milk, dill, parsley, remaining 1/4 teaspoon salt and 1/8 teaspoon black pepper. Return the onions to the skillet along with the Kalamata olives. Pour the egg mixture into the skillet. Stir to combine ingredients. Cook over low heat without stirring for 2 to 3 minutes to allow eggs to set on the bottom.
