• 1/2 cup barley
• 1 1/2 teaspoons kosher salt , plus more to taste
• 2 cups arugula , loosely packed
• 3 scallions , roughly chopped
• 1/2 teaspoon minced garlic (about 1/2 clove)
• 1 cup parsley leaves , loosely packed
• 1 small jalapeno , seeded and minced
• 3 tablespoons olive oil
• 1/4 cup lemon juice (about 2 lemons), plus more to taste
• 1/2 teaspoon black pepper
• 3/4 cup (about 4 ounces) crumbled feta cheese

Place barley, 1/2 teaspoon salt and 2 1/2 cups water in a medium saucepan. Bring to a boil, then reduce heat to medium-low. Simmer until grains are tender but chewy, about 30 minutes. Drain and rinse under cold water until cooled. Set aside.

In the bowl of a food processor, combine arugula, scallions, garlic, parsley and jalapeño. Process until finely chopped, scraping mixture down sides of bowl as needed. Add olive oil, lemon juice, remaining 1 teaspoon salt and pepper and pulse until blended.

In a bowl, combine arugula mixture with barley and feta. Season with additional salt or lemon juice, if desired.
