Preheat oven to 425 degrees. Place bulgur in a heatproof bowl, add boiling water, and stir. Cover tightly, and refrigerate until liquid has been absorbed, about 1 hour.
Combine chopped herbs. Toss tomatoes with garlic, vinegar, 1 teaspoon oil, and 2 tablespoons chopped herbs on a rimmed baking sheet, and roast until tomatoes begin to soften, about 12 minutes. Let cool.
Add roasted-tomato mixture, remaining chopped herbs, scallions, lemon juice, salt, pepper, and remaining 2 teaspoons oil to bulgur, and gently toss. Garnish with whole herb leaves.
