For the vinaigrette, combine the lemon juice, olive oil, lemon zest and salt and pepper to taste in a small bowl. Whisk until combined. Set aside.
In a large pot, bring 6 quarts of salted water to a boil. Add the green beans and cook for 4 minutes. Drain and place the beans in a serving dish. Toss with the vinaigrette and almonds and serve.
