01 - Combine rice, water, and salt in a saucepan. Bring to a boil over high heat, then reduce heat to low, cover, and simmer for 15–20 minutes until rice is tender and liquid is absorbed. Remove from heat and let stand covered for 5 minutes. Fluff with a fork and set aside.
02 - Whisk together tahini, lemon juice, olive oil, minced garlic, water, salt, and pepper in a small bowl until smooth and creamy. Add additional water, 1 teaspoon at a time, if dressing is too thick. Set aside at room temperature.
03 - Halve the cherry tomatoes. Dice the cucumber and red bell pepper into ½-inch pieces. Finely slice the red onion into thin strips. Rinse and pat dry the baby spinach or mixed greens.
04 - Open the can of chickpeas and pour into a colander. Rinse thoroughly under cold running water for 30 seconds. Shake well to remove excess liquid and set aside.
05 - Divide the cooked rice evenly among four serving bowls, creating a bed in the center. Arrange the cherry tomatoes, cucumber, bell pepper, red onion, and spinach in sections around the rice.
06 - Top each bowl with an equal portion of chickpeas, Kalamata olives, and crumbled feta cheese. Add a generous dollop of hummus to the center of each bowl.
07 - Drizzle the lemon-tahini dressing evenly over all four bowls. Sprinkle with chopped fresh parsley and serve immediately with lemon wedges on the side.
