Besides knowing how to use a can opener, there's no need for any special talents when you make this easy three bean salad. And with a homemade dressing, this pantry salad is a classic potluck favorite that can be made in 15 minutes or less.
Drain each can of beans in a strainer and rinse with cool water and shake gently to drain then add to a mixing bowl.
Thinly slice the yellow onion and add to the bowl.
Whisk the vinegars and sugar in a small bowl with the canola oil and kosher salt. Pour over the beans and onion and toss lightly.
Refrigerate for 2 hours or overnight and serve chilled or at room temperature.
