Cook the Quinoa: Rinse the quinoa thoroughly under running water to remove its natural bitterness. In a medium saucepan, combine 1 cup of quinoa with 2 cups (480 ml) of water. Bring to a boil, then reduce the heat to low, cover, and simmer for 15 minutes or until the water is fully absorbed.
Cool the Quinoa: Once cooked, transfer the quinoa to a fine-mesh strainer to remove any excess water. Spread the quinoa on a large plate or tray and let it cool completely. This step ensures the quinoa does not make the salad soggy.
Prepare the Vegetables: While the quinoa is cooling, chop the red bell pepper, tomato, red onion, cucumber, and green onion as specified in the ingredients list.
Mix the Salad Base: In a large mixing bowl, combine the cooked and cooled quinoa, chickpeas, red bell pepper, tomato, red onion, cucumber, green onion, and black olives.
Make the Dressing: In a small bowl, whisk together the lime juice, apple cider vinegar, olive oil, dried oregano, salt, and black pepper until well combined.
Assemble the Salad: Pour the dressing over the quinoa and vegetable mixture. Toss gently but thoroughly to ensure all ingredients are evenly coated.
Add Final Touches: Stir in the fresh mint leaves and crumbled cottage cheese. Adjust seasoning if needed.
Serve: Divide the salad into four portions and serve immediately. Alternatively, refrigerate for up to two hours before serving for a chilled version.
