1 tablespoon olive oil
1 ¼ cup red onion, diced
Juice of 1 lemon

Toss the baby potatoes with olive oil, salt and pepper. Roast at 375 degrees for 15-18 minutes, or until tender.
Meanwhile, in a small pot of boiling water, add the green beans and cook for approximately 2 minutes. Remove and immediately place in an ice bath. After the ice bath, sprinkle with salt and pepper and chop into 1 inch pieces.
In a bowl add the arugula, potatoes, cherry tomatoes, cucumbers, red onion, olives, capers, hard boiled eggs and tuna. Mix dressing and pour over salad. Toss and season with additional salt and pepper, as desired. Serve immediately.
