Put oil and butter in cast iron skillet and heat on medium heat
Whisk eggs and then add cream and whish together with spices, set aside
Put sliced green onions into melted, hot butter and stir while cooking for 1 minute
Add egg mixture to hot skillet
Add cheese and cooked bacon to egg mixture in pan and stir together
Turn heat down a bit and let cook for about 4-5 minutes. Working your way around the skillet, pull the egg from the side, letting the liquid egg mixture move to the sides. Do this twice.
Put cast iron skillet into the oven and let cook until the mixture is cooked through, about 20 - 25 minutes.
Let sit for about 3 minutes and then cut into pie shaped pieces and serve. Garnish with chives
Notes
You can add other veggies to this recipe. I have added cherry tomatoes cut in half, spinach, asparagus, and broccoli. All of this would go into the skillet with the onions so that it can cook a bit before you cover it with egg mixture. I will cook a little longer until spinach is wilted and other vegetables are a bit more cooked if I'm adding more than green onions.
