This recipe is adapted from Heidi Swanson’s Super Natural Every Day, which means it focuses on wholesome, natural ingredients with straightforward techniques. To keep these quinoa patties vegetarian, you can substitute regular Parmesan cheese with a vegan Parmesan alternative. Using gluten-free breadcrumbs makes this recipe friendly for those with gluten sensitivities. When cooking, use a non-stick skillet and cook on medium-low heat to avoid burning while ensuring the patties cook through completely. Make sure to steam and thoroughly drain the spinach to prevent excess moisture, which can make the patties too soft.
