Boil red potatoes. I like to boil and then broil the potatoes in a hot oven or air fryer to make them crisp, but the extra work is optional. While potatoes are boiling, wash the spinach and arugula. Place in a medium mixing bowl. Add 1 tbsp of dressing, toss together, and set aside.
Boil water in a medium pot to blanch the green beans. When water is boiling, drop the green beans into boiling water. When green beans turn bright green, remove and place in an ice bath to cool and preserve the beautiful color.
Arrange greens on a plate, add bean salad, potatoes, green beans, tomatoes, olives, hearts of palm, and remaining vinaigrette on the side. Enjoy! Serves 2.
