How to Make It
Combine the first 8 ingredients in a bowl, and stir with a whisk until blended.
Heat the olive oil in a large nonstick skillet over medium heat. Add chopped leek, carrot, and chopped green onions, and sauté for 5 minutes or until tender. Add the egg mixture; cover and cook over low heat for 8 minutes or until the frittata is almost set.
