01 - Warm 1 tablespoon olive oil in a large skillet over medium heat. Add the sliced red onion and sauté for 2-3 minutes until softened and translucent.
02 - Add the drained chickpeas to the skillet and cook for another 3-4 minutes, stirring occasionally, until heated through and slightly golden.
03 - Add the fresh spinach to the skillet and cook for 1-2 minutes, stirring gently, until just wilted. Remove from heat immediately to preserve texture.
04 - In a small bowl, whisk together the remaining olive oil, lemon juice, minced garlic, dried oregano, salt, and black pepper until emulsified.
05 - In a large mixing bowl, combine the cooked quinoa or rice (if using), sautéed chickpea mixture, cherry tomatoes, diced cucumber, olives, parsley, and mint. Toss gently to distribute evenly.
06 - Drizzle the lemon dressing over the bowl and toss again until everything is well coated. Divide among serving bowls, top with crumbled feta cheese if desired, and serve with lemon wedges.
