Step 1

Heat a medium saucepan over medium-high. Swirl in 2 tablespoons oil. Add onion, garlic, and 1 teaspoon salt; cook, stirring occasionally, until fragrant and translucent, 3 to 4 minutes. Transfer mixture to a large bowl. Return saucepan to medium-high heat with 1 tablespoon oil and rice. Cook, stirring occasionally, until nutty and golden in places, 2 to 3 minutes. Add 2 1/4 cups water; bring to a boil. Stir once, reduce heat to low, and cover. Cook until rice is tender and water has been absorbed, 35 to 40 minutes. Remove from heat; let stand, covered, 5 minutes.

Step 2

Transfer rice to bowl with onion mixture; let cool about 20 minutes. Stir in tomatoes, cucumbers, vinegar, and remaining 1/4 cup oil. Season with salt and pepper. Fold in cheese, parsley, and mint; serve.
