01 - Bring a large pot of salted water to a boil. Add green beans and blanch for 2 to 3 minutes, until bright green and just tender. Drain and immediately plunge into ice water to stop cooking. Drain again and pat dry.
02 - In a large skillet over medium heat, toast the sliced almonds, stirring frequently, for 2 to 3 minutes until golden and fragrant. Transfer to a plate and set aside.
03 - In the same skillet, heat olive oil over medium heat. Add minced garlic and sauté for 1 minute until fragrant, taking care not to brown.
04 - Add the blanched green beans to the skillet. Toss to coat with garlic and oil, sautéing for 3 to 4 minutes until heated through.
05 - Sprinkle in lemon zest, lemon juice, salt, and black pepper. Toss well to combine and heat for another 1 to 2 minutes.
06 - Transfer the green beans to a serving dish, sprinkle with toasted almonds, and serve immediately.
