Pre-heat the oven to 415°. In a 12.5 inch cast iron skillet melt the oil on medium-high heat then cook the chopped onions and garlic. Add the thyme and oregano to the onions and cook until the onions are almost translucent (about 2-4 minutes).
In a separate large mixing bowl beat eggs, then add tomato sauce, milk alternative, salt and pepper and mix. Slice the tomatoes like you would for a sandwich and chop 1 stalk of green onion then set aside.
Add the spinach to the skillet, then stir and cook until slightly wilted (about 1 minute).
Turn the heat down to medium low then add the egg mixture to the pan and mix so everything is evenly distributed. Sprinkle the chopped green onions on top of the eggs and place about 4 sliced tomatoes on top evenly distributed).
Use a pot holder to transfer the pan to the oven and cook for about 10-15 minutes until firm.
