Boil a large pot of water with 1 tsp. of sea salt over a medium to high flame.
For the dressing, mix all the ingredients together in a a dressing jar or a mason jar. Shake to combine.
Once the water is boiling add the potatoes for 10-12 minutes. You want to be able to just put a fork through them. Then add the green beans for 2-3 minutes. Strain immediately.
Add the parsley, olives and onions to a large serving bowl and then top with the warm green beans and potatoes. Drizzle 1/4 - 1/3 of the dressing over everything and toss.
Serve with additional sea salt and fresh cracked pepper as desired. Enjoy!
