Crack the eggs into a large mixing bowl, and beat with a fork to break up the yolks and combine them with the whites. Do not use an electric beater. A fork gets the job done just right.
OPTIONAL STEP: you can sauté your veggies now in a little bit of oil to bring out more flavor if you wish. Cool them before adding to the eggs. Or, skip this and move to the next step.
Combine the veggies, parsley, cheese and eggs and stir well to combine.
Oil an 8 or 9-inch ceramic tart pan, set it on a baking tray (for easier handling in the oven), and pour the egg mixture into it.
Bake for about 30 minutes (time can vary by oven), or until the egg is fully cooked.
Cool on a wire rack.
Slice like a pie and serve.
Delicious toppings are a small dollop of sour cream, sliced avocado or even some hummus.
