01 - Bring a large pot of salted water to a boil. Add green beans and cook for 3-4 minutes until bright green and just tender. Drain and immediately plunge into ice water to stop cooking. Drain again and set aside.
02 - In a large skillet over medium heat, add sliced almonds. Toast, stirring frequently, until golden brown and fragrant, about 2-3 minutes. Transfer to a plate and set aside.
03 - In the same skillet, heat olive oil over medium heat. Add minced garlic and sauté for 30 seconds until fragrant, but not browned.
04 - Add green beans to the skillet. Toss to coat with garlic and oil. Sauté for 2-3 minutes until heated through.
05 - Add lemon zest, lemon juice, salt, and black pepper. Toss well to combine.
06 - Sprinkle toasted almonds over the green beans just before serving.
