Creating Chickpea Arugula Quinoa Salad is straightforward if you follow these simple steps:

1. Rinse Quinoa: Place the quinoa in a fine mesh strainer and rinse under cold water for about 2 minutes.
2. Cook Quinoa: In a medium saucepan, combine rinsed quinoa and water. Bring to a boil, then reduce to a simmer. Cover and cook for 15 minutes or until the quinoa is fluffy. Remove from heat and let it cool.
3. Prepare Vegetables: While the quinoa is cooking, chop the arugula, cherry tomatoes, cucumber, and red onion.
4. Combine Ingredients: In a large mixing bowl, combine the cooked quinoa, chickpeas, arugula, tomatoes, cucumber, and red onion.
5. Make Dressing: In a small bowl, whisk together the olive oil, lemon juice, salt, and pepper.
6. Dress the Salad: Pour the dressing over the salad and toss gently to combine, ensuring all ingredients are coated.
7. Add Feta: If using, sprinkle crumbled feta cheese over the top of the salad and give it a light toss.
8. Serve or Chill: Serve immediately or refrigerate for about 30 minutes to allow flavors to meld.
