You will need a skillet that is NOT non-stick, and can go from stove top to oven (cast iron or stainless steel would be best).
Melt a couple tablespoons of butter in the pan on medium heat and then saute your toppings (onion, garlic, carrots, broccoli, squash, spinach, etcetera - i.e. anything you might like or that is leftover in your produce drawer).
Meanwhile whisk 6 eggs together in a bowl and add a good amount of some grated cheese.
Take your sauted mix of veggies and add them into the bowl of eggs and cheese. Melt a little more butter in the pan and then pour the whole egg-cheese-veggie mixture back into the pan
and cook for 5 minutes. Add another good amount of cheese over the top of the mixture and move the pan into the oven set on broil for 5 minutes.
Remove, slice into wedges, serve (perhaps with a little dollop of cultured creme, diced tomatoes, avocado slices, and some cilantro) and enjoy!
