01 - Rinse rice under cold running water until it runs clear. Combine rice, 2 cups water, and 1/2 teaspoon salt in a medium saucepan. Bring to a rolling boil over high heat, then reduce to low, cover tightly, and simmer for 15 to 18 minutes for white rice or 35 to 40 minutes for brown rice, until grains are tender and liquid is fully absorbed. Remove from heat, fluff with a fork, and let stand uncovered.
02 - In a small bowl, whisk together the olive oil, fresh lemon juice, minced garlic, dried oregano, 1/2 teaspoon salt, and black pepper until emulsified. Set aside.
03 - Halve the cherry tomatoes, dice the English cucumber, chop the red bell pepper, thinly slice the red onion, and finely chop the fresh parsley.
04 - In a large mixing bowl, toss together the prepared tomatoes, cucumber, bell pepper, red onion, chickpeas, Kalamata olives, and parsley. Drizzle with half of the dressing and toss gently to coat evenly.
05 - Divide the cooked rice among four serving bowls. Spoon the dressed vegetable and chickpea mixture over each portion of rice. Crumble feta cheese generously over each bowl.
06 - Drizzle the remaining dressing over each assembled bowl. Serve immediately at room temperature, or refrigerate for 20 minutes for a chilled version.
