01 - Bring a large pot of salted water to a boil. Add green beans and cook for 2-3 minutes until bright green and just tender. Drain and immediately transfer to a bowl of ice water to stop cooking. Drain again and set aside.
02 - In a large skillet over medium heat, toast the sliced almonds, stirring frequently, until golden brown and fragrant, approximately 2-3 minutes. Transfer to a plate.
03 - In the same skillet, heat olive oil over medium heat. Add minced garlic and sauté for 30 seconds until fragrant, being careful not to brown.
04 - Add the drained green beans to the skillet. Toss to coat with garlic and oil. Cook for 3-4 minutes, stirring occasionally, until heated through.
05 - Add lemon zest and juice, season with salt and pepper, and toss well. Remove from heat.
06 - Sprinkle toasted almonds over the green beans just before serving.
