We love how arugula pairs with this fresh tuna salad. You can stir 2 cups shredded arugula into the salad and serve it on crackers.
Stir together first 12 ingredients in a large bowl. Cover and chill until ready to serve. Serve with flatbread, arugula, and feta.
Note: For testing purposes only, we used StarKist Flavor Fresh Pouch Chunk Light Tuna In Water.
