In a large pan add 4 or 5 tablespoons of Olive Oil and sauté Mushrooms, Bell Pepper, Corn, Leek, Parsley for about 10 minutes.
Grease a small baking pan with olive oil and add in the vegetables.
In a large bowl add in the Eggs, Feta Cheese, Milk and beat. Adding salt or pepper is up to you. I did not any because the Feta Cheese I bought was already a bit to salty.
Add the Egg mixture into the pan and bake at 180 for 35 minutes or until golden brown.
