Heat oil and garlic in a small skillet over medium heat; cook 2 minutes, stirring occasionally. Remove from heat; cool slightly. Combine garlic mixture, 1 tablespoon nuts, vinegar, 1/4 teaspoon salt, pepper, and basil in a food processor; pulse until well combined.
Cook beans in boiling water 4 minutes or until crisp-tender; drain. Rinse under cold water; drain. Place in a large bowl. Add basil mixture and remaining 1/4 teaspoon salt; toss to coat. Sprinkle with 2 tablespoons nuts and tomatoes.
I made this recipe shortly after the May 09 issue came out and have made it numerous times since. This recipe is awesome and even my husband agrees and he really isn't into eating vegetables. Would make this again and again!
