Soak uncooked quinoa for 6-8 hours.
Preheat oven to 425 degrees F. Line a 12-cup muffin tin with strips of parchment paper and drizzle 1/4 teaspoon of oil in the center. Spread around with your finger until evenly coated and set pan aside.
Thoroughly rinse quinoa, then add to a blender. Add remaining crust ingredients (1 tablespoon of oil should remain) and blend on high until smooth and creamy. It should resemble a thick pancake batter.
Pour 1 tablespoon of batter into prepared each muffin tin and bake for 10 minutes. Remove pan, flip crusts onto a baking sheet and return to oven baking for another 5 - 10 minutes until browned and edges are crispy.
Remove baking sheet from oven and top each pizza round with 1 teaspoon of sauce. Add a layer of cheese and then a slice of pepperoni, and bake for 8 - 10 minutes until the cheese has melted and started to brown.
Remove, let cool for a few minutes on the pan.
Garnish with herbs, pepper flakes, grated cheese, etc., (totally optional) and serve immediately!
