Farro (or Barley) a la Greque

This is basically a Greek salad with some complex carbohydrates added. Very hearty and wonderful for summer. 

Ingredients

• 1 cup barley (3 cups water). Or farro (I couldn't find it), or wheatberry. 
• 5 ounces Kalamata olives (in water), diced
• 1/2 english cucumber, cut into a 1/4" dice
• 2 medium tomatoes, cut into a 1/4" dice
• 4 ounces crumbled feta (Mt. Vikos, preferably) packed in wter
• Pesto Sauce to taste (1/4 to 1/2 cup)
• Salt and pepper to taste

Preparation

Bring barley and water to a boil, then simmer covered for 1 hour. Test and see if chewy. Don't wait till soft. Place barley in a colander and rinse in cold water to stop cooking, and remove the excess glutens. Toss to get rid of the excess water. Mix in all other ingredients, and adjust flavorings (salt, pepper, pesto) to taste.
