Three Bean Salad is a classic summer potluck recipe made with green beans, wax beans, and kidney beans tossed in a sweet and sour dressing.
Bring a large pot of salted water to a boil (add enough salt that the water taste like salt water).
Place the trimmed and cut wax beans and green beans in the pot and cover with a lid. Cook for 4-5 minutes or until they reach the desired level of tenderness.
Drain and rise beans with cool water. Pat dry to remove some of the excess water and set aside.
Drain and rinse the kidney beans.
In a small bowl combine vinegar, sugar, olive oil, ½ teaspoon of kosher salt, and black pepper. Whisk together.
In a large bowl combine the wax beans, green beans, kidney beans, and onion. Pour the dressing over them and lightly toss together.
Store in the refrigerator covered until you are ready to serve.
