Bring a large pot of salted water to a boil.
Add the beans and boil for 3 minutes only.
Drain and add to a cold water bath or simply run them under cold water to stop the cooking process.
Make a lemon vinaigrette by combining one part extra-virgin olive oil with one part of fresh lemon juice.
Season with salt, pepper and fresh thyme leaves.
Shake well in a jar and pour as much as you want over the beans.
Check for seasoning and garnish with lemon slices and lemon zest.
