Ingredients

2 small red new potatoes

Coarse salt and freshly ground pepper

1/4 pound green beans, trimmed and cut into thirds

1/4 cup oil-cured black olives, such as Moroccan

1 rib celery, thinly sliced on the bias

1 hard-boiled egg, finely chopped

1 tablespoon coarsely chopped fresh dill

1 (7.76-ounce) jar Italian olive oil-packed tuna

Caper Vinaigrette

Preparation

Place potatoes in a medium saucepan with enough water to cover; bring to a boil over medium-high heat. Immediately reduce heat to a simmer; cook until potatoes are easily pierced with the tines of a fork, about 15 minutes. Drain, cool, and cut into quarters.

Meanwhile, bring a medium saucepan of salted water to a boil over high heat. Prepare an ice-water bath; set aside.

Add green beans to boiling water and cook until tender, about 4 minutes. Immediately transfer to ice-water bath to cool; drain.

Place potatoes, green beans, olives, celery, egg, dill, and tuna in a large bowl. Add vinaigrette and toss to combine; season with salt and pepper.
