Red Potato, Asparagus, and Artichoke Salad

9 small red potatoes
1.5 lb. fresh asparagus, trimmed
14 oz. canned artichoke hearts, drained and quartered
1.5 T. Dijon mustard
1/8 c. fresh lemon juice
3/8 c. olive oil
salt and pepper
1/8 t. cayenne pepper
2.5 T. minced fresh chives

Place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender (about 20 minutes). Drain and allow to steam dry for a minute or two. Allow to cool completely before cutting into bite-size cubes. Transfer to a large bowl.

Bring a large pot of salted water to a boil over high heat. Add the asparagus spears and cook until tender (about 3 minutes). Drain and immediately plunge into cold water to stop cooking. Cut the asparagus spears into 1" pieces. Place in the bowl with potatoes. Stir in the artichokes, breaking them apart slightly as you put them in the bowl.

Combine the mustard and lemon juice in a bowl; whisk the oil gradually into the mustard and lemon juice until smooth. Season with salt, pepper, and cayenne to taste. Drizzle over the vegetables; toss to coat. Sprinkle with chives to serve.

Serves 8.
