Preparation Bring 4 cups water to a boil in a 2-quart heavy saucepan with lentils, garlic, and 1/2 teaspoon salt, then reduce heat and simmer, uncovered, until lentils are just tender, 15 to 25 minutes. Drain in a large sieve, then transfer to a large bowl. Toss hot lentils with tomatoes, scallions, dill, basil, vinegar, oil, pepper, and remaining 1/2 teaspoon salt, or to taste.
