Bring a large pot of water to a boil. Add enough salt to make it taste like the ocean.
Fill a large mixing bowl with ice water and set aside.
Place the mixing bowl of ice water next to the stove. Add the green beans to the pot of boiling water and cook for 3-4 minutes. Using the spider strainer remove the beans from the pot and immediately plunge them into the ice water. This might need to be done is 2-4 batches depending on the size of the pot.
Once all of the beans are in the ice water heat the oil in the skillet over medium high heat. Add the shallots and cook until they are translucent and have softened stirring occasionally. While the shallots are cooking drain the ice water from the bowl.
Add the garlic and cook for a minute. Then add the green beans, salt, pepper, and sauté until done, about 4-7 minutes.
