In a large mixing bowl, combine the beans, chopped peppers, onions, capers, and fresh herbs. Mix using a wooden spoon.
In a small bowl, add the vinaigrette ingredients. Whisk vigorously to combine.
Add the vinaigrette to the salad bowl. Toss to coat.
For best results, cover and refrigerate for a bit before serving so that the beans soak up the vinaigrette flavors. Give the salad another quick toss before serving.
Recipe Note
If you prefer, hold the mint and basil until you are ready to serve the salad. This will keep them from wilting into the salad, but the flavors won’t be as intense.
