Rinse quinoa and add to a small pot with ⅔ cup water and a pinch of salt.
Simmer over medium heat, uncovered, for 15 minutes until water is mostly absorbed.
Turn off heat, cover with lid, and let stand for 5 minutes; remove lid and fluff quinoa with a fork.
Dry chickpeas well using a kitchen towel and toss with olive oil and seasonings.
Air fry at 400°F (200°C) for 10-12 minutes, shaking halfway; or roast in oven at 425°F (220°C) for 18-20 minutes, stirring halfway.
Turn off heat and let chickpeas rest inside for 5 minutes to crisp up.
Prepare the salad by chopping cucumber and tomatoes, finely dicing onion, then tossing with olive oil, vinegar or lemon juice, oregano or mint, salt, and pepper.
Assemble bowls with ½ cup quinoa, ⅓ cup chickpeas, ¼ cup hummus, salad, feta cheese, and olives arranged separately.
Drizzle with olive oil and serve fresh.
