Instructions
Prepare tomatoes
Heat oven to 300°F. Halve tomatoes through stem ends and arrange, cut sides up, in 1 layer on a large baking sheet. Add garlic to pan and drizzle both tomatoes and garlic lightly with oil (about 1 tablespoon). Sprinkle with salt. Roast in middle of oven until tomatoes are slightly shriveled around edges, about 1 hour. Cool in pan on a rack 20 to 30 minutes.
Make Couscous
Meanwhile, bring broth to a boil in a 3-quart heavy saucepan and stir in couscous, then simmer, uncovered, 6 minutes. Cover pan and remove from heat. Let stand 10 minutes. Spread couscous in one layer on a baking sheet or plate and cool 15 minutes.
Dressing
When the tomatoes are done and cooled slightly, peel garlic and puree with 1/4 cup oil, water, lemon juice, 1 teaspoon salt, 1/4 pepper, and 1/2 cup roasted tomatoes in a blender until dressing is very smooth. Adjust seasonings to taste.
Assemble and Serve
Transfer cooled couscous to a bowl and stir in olives, remainder of the roasted tomatoes, herbs, and dressing. Season to taste with more salt and pepper as needed.
