French Chicken Salad

After my good friend had me make this for my other good friend'a baby shower, it's gotten lots of love. Including for a Point Reyes picnic.

• 4 chicken breasts, poached
• 2 tablespoons olive oil
• Kosher salt
• Freshly ground black pepper
• 1/4 cup small-dice red onion
• 2 tablespoons red wine vinegar
• 1 cup small-dice tart apple, such as Granny Smith
• 2/3 cup small-dice celery (from about 2 medium celery stalks)
• 2/3 cup mayonnaise
• 3 tablespoons finely chopped fresh tarragon leaves

Poach chicken, and dice.

Dice all other ingredients and add to bowl. 

Enjoy!
