1. Place barley and 4 cups water in a medium saucepan; bring to a boil. Cover, reduce heat to low, and cook until water is nearly absorbed, 25-30 minutes. Stir in edamame and peas
and cook, uncovered, until barley absorbs all
of the remaining water, 5-10 minutes. Remove from heat.
2. Stir in spinach; set aside. Combine Worcestershire sauce, lemon zest, lemon juice, and sea salt in a small bowl, whisking well. Pour vinaigrette over barley; stir to combine. Serve warm or at room temperature.
