# How to Make It:

01 - Preheat oven to 375°F. Lightly grease a 9x9-inch baking dish with oil or butter.
02 - Combine quinoa and vegetable broth in a medium saucepan. Bring to a boil, reduce heat, cover, and simmer for 15 minutes until liquid is absorbed. Fluff with a fork and set aside.
03 - Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3 minutes until translucent.
04 - Stir in minced garlic and sliced mushrooms. Cook for 6 to 7 minutes until mushrooms are soft and moisture has evaporated. Add spinach and sauté for 1 minute until wilted. Remove from heat.
05 - Melt butter in a separate saucepan over medium heat. Whisk in flour and cook for 1 minute. Gradually add milk and heavy cream, whisking until the sauce thickens, about 3 to 4 minutes.
06 - Remove pan from heat. Stir in Parmesan, nutmeg, salt, and black pepper until fully incorporated and smooth.
07 - In a large mixing bowl, combine cooked quinoa, sautéed vegetables, and Alfredo sauce. Mix thoroughly to distribute ingredients evenly.
08 - Transfer mixture into the prepared baking dish. Sprinkle mozzarella and additional Parmesan evenly over the surface.
09 - Bake for 20 to 25 minutes until golden and bubbling.
10 - Allow to rest for 5 minutes before serving. Garnish with chopped parsley if desired.
