Preparation

• To roast the tomatoes—Heat the oven to 350°F. Coat the tomato halves with the olive oil, season them lightly with salt and pepper, and arrange them, cut side down, on a parchment-lined rimmed baking sheet. Roast for about 2-1/2 hours. The tomatoes should be very concentrated and browned, and most of their juices will have cooked off. (The tomatoes can be cooked a day or two ahead and refrigerated; before serving, bring to room temperature.)
• To make the salad—In a bowl, combine the bulgur, boiling stock, and half the olive oil; cover and let stand for at least 30 minutes. Uncover and fluff with a fork. Stir in the remaining olive oil, the parsley, mint, scallion, garlic, lemon juice, and zest. Taste and add salt and pepper as needed.
• To serve—Mound the tabbouleh in the middle of each plate and arrange the roasted tomatoes around the tabbouleh. Garnish with the pine nuts and sprigs of mint.
