Grease a 9 x 12 inch baking dish with butter or coconut oil.
In a medium sized bowl, mix oats, quinoa, flax, pecans, apple, cinnamon, nutmeg, salt, and baking soda.
In a separate bowl, mix maple syrup, milk, vanilla, and egg. Use a whisk or electric mixer to mix thoroughly.

Bake for 40 - 45 minutes. Remove from oven and let cool for 5 minutes before serving. If desired, sprinkle an additional 1/4 cup of toasted chopped pecans to the top before cutting and serving.
