Ingredients

- 2 cups fresh spinach (or thawed frozen spinach, drained)
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 2 cups vegetable broth
- 1 tablespoon olive oil
- ½ cup feta cheese or shredded mozzarella (optional)
- 1 teaspoon cumin
- 1 teaspoon paprika
- Salt and black pepper to taste
Optional additions:

Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 180°C (350°F). Lightly grease a medium baking dish to prevent sticking.
2. Cook the Quinoa
Rinse the quinoa under cold water to remove bitterness. In a saucepan, combine quinoa with 1 cup of vegetable broth. Bring to a boil, then reduce heat and simmer for about 12–15 minutes until fluffy and the liquid is absorbed.
3. Cook the Lentils
In another pot, cook lentils in water or broth until tender but not mushy, about 20 minutes. Drain any excess liquid and set aside.
4. Prepare the Spinach Mixture
Heat olive oil in a large pan over medium heat. Add chopped onion and cook until soft and translucent. Stir in minced garlic and cook for another minute. Add spinach and sauté until wilted. Season with cumin, paprika, salt, and black pepper.
5. Combine the Ingredients
In a large mixing bowl, combine cooked quinoa, lentils, and the spinach mixture. Stir gently until everything is evenly distributed.
6. Assemble the Bake
Transfer the mixture into the prepared baking dish. Spread evenly and sprinkle cheese on top if using.
7. Bake
Place the dish in the oven and bake for 25–30 minutes, or until heated through and lightly golden on top.
8. Cool and Serve
Let the bake rest for a few minutes before slicing. Garnish with fresh parsley if desired and serve warm.
