01 - Rinse rice under cold running water until the runoff turns clear. Combine rice, 2 cups water, and 1/2 teaspoon salt in a medium saucepan. Bring to a rolling boil over medium-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 the grains are tender and all liquid has been absorbed. Remove from heat and fluff gently with a fork.
02 - In a small mixing bowl, whisk together the olive oil, fresh lemon juice, minced garlic, dried oregano, remaining 1/2 teaspoon salt, and black pepper until fully 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. Drain and rinse the canned chickpeas under cold water. Pit and halve the Kalamata olives.
04 - In a large mixing bowl, combine the prepared tomatoes, cucumber, bell pepper, red onion, chickpeas, olives, and parsley. Pour half of the dressing over the mixture and toss thoroughly to coat every component evenly.
05 - Divide the cooked rice evenly among four serving bowls. Spoon the dressed vegetable and legume mixture over each portion of rice. Finish by crumbling feta cheese generously over each bowl.
06 - Drizzle the remaining dressing over the assembled bowls. Serve immediately at room temperature, or refrigerate for 20 to 30 minutes for a chilled serving option.
