Bean & Barley Salad (A Low Glycemic recipe)

Very similar to a cold spaghetti salad! I made this a few times and have adjusted the type of beans and amounts to my taste. I've used garbanzos & black beans and strong onion. I would add a medium sweet onion if I had it on hand. It's a refreshing mix and makes enough to last the week (easy for pack lunches). Adjust amounts to your liking: can of kidney beans, Northern beans (rinse & drain), diced tomatoes. Add cooked barley - rinse & drain, diced celery, diced bell peppers. For seasoning: add splash of Balsamic vinegar, Wishbone Balsamic Vinaigrette (enough to moisten salad), and 1/2 bottle of McCormick's "salad supreme." Optional: minced onion
