In a medium sauce pan, bring the onion, garlic, sea salt, pepper, rinsed quinoa and water to a boil. Cover and reduce heat to a simmer for 10-15 minutes, until all the liquid is absorbed. Remove from heat and set aside for 5 minutes
Preheat your oven to 350
Meanwhile, in a large mixing bowl, whisk together the eggs and milk. Stir in 1 ½ cups of cheese and 1 tbsp of chili flakes, then fold in the cooked quinoa
Pour the mixture (it will be ‘soupy’) into a 9x13 baking dish and sprinkle the remaining cheese and chili flakes over top
