Ingredients
Servings
4
- 1 cup quinoa (rinsed)
- 2 cups water
- 1 tablespoon olive oil (plus extra for frying)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 4 cups fresh spinach, roughly chopped
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon ground cumin
- 1 teaspoon lemon zest
- 1 large egg, beaten
- 3/4 cup crumbled feta cheese
- 1/3 cup whole wheat breadcrumbs (or gluten-free alternative)
- Salt to taste
- 2 large roasted red bell peppers (jarred or freshly roasted and peeled)
- 1 tablespoon olive oil
- 1 garlic clove
- 1 tablespoon lemon juice
- 1/4 teaspoon smoked paprika
- Salt and pepper to taste
Instructions
-
Cook the quinoa: In a medium saucepan, bring 2 cups of water to a boil. Add the rinsed quinoa, reduce heat to low, cover, and simmer for 15 minutes or until the water is absorbed and the quinoa is tender. Remove from heat and fluff with a fork. Let cool slightly.
-
Prepare the spinach mixture: Heat 1 tablespoon olive oil in a skillet over medium heat. Add the finely chopped onion and cook for 3-4 minutes until translucent. Add minced garlic and cook for 1 more minute until fragrant. Stir in the chopped spinach and cook until wilted, about 2-3 minutes. Season with salt, ground black pepper, smoked paprika, and cumin. Remove from heat and let cool.
-
Combine the quinoa cake mixture: In a large bowl, mix the cooked quinoa, sautéed spinach and onion mixture, lemon zest, beaten egg, crumbled feta cheese, and breadcrumbs until well combined. If the mixture feels too wet, add additional breadcrumbs to achieve a moldable consistency.
-
Form and cook the cakes: Shape the mixture into 8 equal-sized patties, approximately 2.5 inches in diameter. Heat olive oil in a non-stick skillet over medium heat. Fry the cakes in batches for 4-5 minutes on each side, or until golden brown and heated through. Drain on paper towels.
-
Prepare the red pepper sauce: In a blender or food processor, combine roasted red bell peppers, olive oil, garlic, lemon juice, smoked paprika, salt, and pepper. Blend until smooth and creamy. Adjust seasoning as needed.
-
Serve the quinoa cakes warm with a generous drizzle or side of the anti-inflammatory red pepper sauce. Store leftovers in the refrigerator for up to 3 days and reheat for quick, healthy meals or snacks.
