Preheat oven to 350°. On a baking sheet mix together the oats, quinoa, and slivered almonds.
While the oven is preheating, In a bowl off to the side whisk together the yogurt, almond milk, cinnamon and honey.
Place the tray into the oven to begin toasting the oat mixture. Set the timer for about 10 minutes, but toast them until they are fragrant and just begin to get some color.
Take the apple and dice it into little squares and keep it off to the side.
Remove the toasted oat mixture from the oven and let cool. Once it has cooled to room temperature combine the dry mix with the milk mixture and apple. Let sit for atleast 3 hrs to soak in the fridge. I like to let it go overnight.
When ready to serve, dish the muesli out and pour almond milk and honey over it to taste. I like to approach it similar to cooked oatmeal and finish it off per person as some like it thicker and sweeter than others.
