01 - Combine quinoa, water, and salt in a medium saucepan. Bring to a boil over medium-high heat, then reduce to low. Cover and simmer for 12 to 15 minutes until the liquid is absorbed. Remove from heat, keep covered for 5 minutes, then fluff with a fork.
02 - In a small bowl, whisk together tahini, lemon juice, olive oil, maple syrup or honey, minced garlic, salt, and black pepper. Gradually add water and whisk until the dressing is creamy and pourable.
03 - While quinoa cooks, halve the cherry tomatoes, dice the cucumber, thinly slice the red onion, halve the Kalamata olives, slice roasted red peppers, and prepare spinach or arugula. Set all vegetables aside.
04 - Evenly divide cooked quinoa among four serving bowls. Arrange spinach or arugula, tomatoes, cucumber, red onion, olives, roasted red peppers, and chickpeas over the quinoa.
05 - Top each bowl with a generous spoonful of hummus and sprinkle with crumbled feta cheese if desired.
06 - Drizzle lemon tahini dressing over the bowls just before serving.
