Grate 2 medium-sized zucchinis and measure out 4 cups worth. Squeeze the zucchini in paper towel to drain out excess moisture.
In a medium bowl, whisk together the eggs, milk, oregano, basil, salt and pepper. Set aside for now.
Turn on the broiler and move the oven rack to the second top position.
Heat a cast iron skillet with a bit of cooking oil. Add the onion, garlic and zucchini. Saute for 10 minutes, or until most moisture is gone from the zucchini.
Pour the egg mixture in and gently stir together. Cook for about 1-2 minutes, or until eggs begin to set slightly and golden on the edges.
Now sprinkle the parmesan on top of the eggs. Remove from heat.
Broil for 2-5 minutes or until top is set and slightly browning. Keep an eye on eggs during this time as they can burn easily.Use a spatula to slice into pieces, serve and enjoy!
