Watermelon and Arugula Salad

I love watermelon and this is a great fresh summer salad, pairing fresh watermelon with peppery arugula. 

2 cups baby arugula leaves*
4 cups seedless watermelon, 3/4-inch-diced
1 tsp sea salt
1/2 tsp freshly ground black pepper
8 ounces good feta cheese, 1/2-inch diced (leave out if going pure paleo)
2 tbsp good balsamic vinegar (I used the stuff from Oliv)

Place the arugula,watermelon, feta, salt and pepper in a large bowl. Mix together and drizzle with balsamic vinegar. 

*Arugula (otherwise known as rocket, roquette, rugula and rucola) is a dark green salad leaf with a slightly bitter, mustardy, peppery flavor. Arugula is a good choice of salad green to accompany a rich dish, because its sharp bite will cleanse the palate. Arugula is a Mediterranean plant—the Romans claimed it was an aphrodisiac—that also grows wild in Asia.
