In a small saucepan, boil 4 cups of water and add 1 cup of whole grain sorghum to make 3 cups of cooked sorghum. Cover with a tight-fitting lid, reduce heat to medium and simmer for 45 minutes or until tender. Fluff with a fork.
Combine all salad ingredients, including cooked sorghum, in a large bowl.
Whisk together all dressing ingredients. Drizzle dressing over salad and toss to coat. Serve with lemon wedges.
