Preheat oven to 375℉. Lightly spray an 7x11 inch baking dish with olive oil.
Heat 2 tsp olive oil in an 12 inch skillet over medium heat. Sauté your scallions for 1 minute. Sauté your spinach until mostly wilted for about 2 minutes. Season with salt to taste. Remove to a colander to drain and pat dry with paper towels to remove excess liquids.
In a large bowl, whisk together the eggs and olive oil. Next, whisk in the milk until combined. Then, sift in the flour, baking powder, salt and mix until just incorporated. Fold in the spinach mixture, sun dried tomatoes, goat cheese, dill, and mozzarella. Transfer mixture to the baking dish and spread out evenly. Sprinkle with parmesan cheese. Bake for 45-50 minutes or until golden brown on top. Allow to cool for 15 minutes.
