Drain and rinse the chickpeas. Lay on a towel and dry them off.
Add the chickpeas to an air fryer or skillet. Spray with olive oil cooking spray and add the Greek seasoning.
Cook for 10 minutes at 400 degrees in the air fryer. If cooking in a skillet cook over medium heat for 7-10 minutes, or until the chickpeas are crunchy.
In a small bowl add the Greek yogurt, shredded cucumber, lemon juice, dill, garlic powder, salt, and pepper. Mix together.
Add 1 1/2 cups of lettuce to each bowl. Top each one with 2 tablespoons of feta cheese, cucumber, cherry tomatoes, red onion, and 2 tablespoons of the tzatziki sauce.
