If using uncooked quinoa: Bring broth and quinoa to boil. Lower heat to lowest setting and simmer while covered for about 20 minutes or until it is fluffy and the tiny curls stick out from the seeds.
Preheat oven to 350 degrees. Coat an 8-by-8-inch glass or ceramic baking dish with olive oil.
In a large medium mixing bowl, whisk egg replacer and water together. Set aside.
Heat 1 tbsp olive oil in a medium pan. Add onion and garlic and sauté until translucent, about 8 minutes.
Add thyme, rosemary, and red-pepper flakes, and spinach and sauté until just wilted. Remove from heat; transfer to the egg mixture.
Add quinoa, sour cream, lemon zest, pepper, and nutritional yeast to the spinach-onion mixture, and stir until well combined.
Pour the mixture into the prepared baking dish, and place in the oven. Bake for 60 minutes, until set and edges are brown. Let cool slightly before slicing. Serve warm or at room temperature (it's also good cold).
