01 - Rinse rice under cold water until it runs clear. Combine rice, 2 cups water, and 1/2 teaspoon salt in a medium saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 15 to 18 minutes for white rice or 35 to 40 minutes for brown rice, until tender and liquid is fully absorbed. Fluff with a fork and set aside.
02 - In a small bowl, whisk together the olive oil, lemon juice, minced garlic, dried oregano, 1/2 teaspoon salt, and black pepper until well combined. Set aside.
03 - Halve the cherry tomatoes, dice the cucumber, chop the red bell pepper, thinly slice the red onion, and chop the fresh parsley.
04 - In a large mixing bowl, combine the prepared tomatoes, cucumber, bell pepper, red onion, drained chickpeas, Kalamata olives, and parsley. Drizzle with half of the dressing and toss gently to coat evenly.
05 - Divide the cooked rice evenly among four serving bowls. Top each with the vegetable and chickpea mixture, then sprinkle crumbled feta cheese over each portion.
06 - Drizzle the remaining dressing over each bowl. Serve immediately at room temperature, or refrigerate for 20 to 30 minutes for a chilled version.
