Preheat oven to 350 and grease the 12" casserole dish.
Mince/chop/grate veggies and layer them into the casserole dish.
Open and whisk 13 eggs in a bowl to make a nice big scramble.
Pour your whisked eggs on top of the veggies.The eggs should cover all the goodies below, or if not add more eggs.
Cook for approximately 35 minutes or until golden brown and puffed up. This might take 5-15 minutes longer depending on the size of your dish and the moisture level of the ingredients- just make sure the eggs have set. Serve warm.
