Bring vegetable broth to a boil in a medium pot. Stir in barley.
Cover and reduce heat; simmer 10 to 12 minutes or until tender. Meanwhile, place kidney beans, bell pepper, zucchini, almonds and scallions in a large salad bowl.
Transfer cooked barley to colander and rinse with cold water (both to cool it down and to keep it from getting sticky).
Transfer cooled, drained barley to salad bowl. Add oil, vinegar, and salt and pepper to taste, and toss well.
*To roast almonds, spread in an ungreased baking pan. Place in a preheated 350° oven and bake 10 minutes or until golden brown and fragrant; stir once or twice to ensure even browning. Note that almonds will continue to roast slightly after removing from oven.
