Pre-heat oven to 400 degrees.
Wash one cup of quinoa, and cook the quinoa with two cups of water. (Bring to a boil, then simmer with lid closed). When cooked, set aside in a large bowl to cool.
Finely chop your aromatics and the sage.
Sautee the aromatics with your frozen spinach and salt, to taste, until spinach is cooked.
Add the spinach mix to the quinoa and stir until the spinach is evenly distributed. Add the cheese to the mixture, and transfer the mixture into a greased 9x9 baking dish.
Evenly pour in the beaten eggs so that the quinoa mixture absorbs it completely.
Top your dish with a generous serving of parmesan before baking for approximately 20 to 22 minutes.
