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 halt cooking. Drain thoroughly.

03 - In the same skillet, add the remaining 1 tablespoon olive oil and minced garlic. Sauté for 30 seconds until fragrant, taking care not to burn the garlic.
04 - Add the blanched green beans to the skillet. Toss to coat in oil and garlic, and sauté for 2 to 3 minutes until heated through.
05 - Incorporate lemon zest, lemon juice, sea salt, and black pepper. Toss thoroughly to combine all flavors.
06 - Remove from heat and sprinkle toasted almonds over the green beans. Serve immediately.
