Trim your fresh green beans and bring a large pot of water to a boil.
Stir in 2 teaspoons of sea salt and once vigorously bubbling, carefully add in your beans using a slotted spoon.
Allow your green beans to boil for just 2 minutes.
Quickly prepare an ice bath and once the beans are done, carefully transfer into the ice bath.
Allow them to sit in the ice bath for just under a minute, then drain well.
This will keep them bright green and tender crisp.
Drizzle your green beans with the butter or oil of your choice, add garlic, lemon zest and juice. Toss well to coat.
Arrange your cooked beans on a platter then sprinkle with your freshly shaved parmesan cheese and freshly ground pepper.
