Cook quinoa according to package directions. Usually, you may or may not have to rinse the quinoa; the Costco kind does not need to be rinsed. Typically, directions include bringing 1 cup of quinoa with 2 cups of water to a boil and then simmering for 15 to 20 minutes until all the water is absorbed. 1 cup of uncooked quinoa will yield 3 cups of cooked quinoa at a minimum. Saute onions and garlic in 1 teaspoon oil until translucent and tender, about 3 minutes.
Preheat oven to 350 degrees. Mix together all ingredients except pizza sauce.
Grease a mini muffin tin with cooking spray or your preferred oil. Then, spoon, one heaping tablespoon of mixture into each cup. Push down with the back of a spoon so that the top of each muffin is flat.
Bake for 15 minutes. Remove from oven and let cool for 10 minutes, then use a butter knife to run the knife around the edges and pop out the bites.
Heat the marinara sauce for dipping and then enjoy!
Notes
To Store: Once the quinoa bites have fully cooled, transfer them to an airtight container and refrigerate for up to 4–5 days. For best texture, reheat in the oven or air fryer to bring back some crispiness, or microwave for a quick option.To Freeze: Let the bites cool completely, then arrange them in a single layer on a baking sheet and freeze for about 1–2 hours (this prevents them from sticking together). Once frozen, transfer to a freezer-safe bag or container. Store in the freezer for up to 3 months.
