In small saucepan, combine beets and enough water to cover. Bring to a boil. Reduce heat; cover and simmer 8 to 12 minutes or until beets are tender. Drain. Rinse with cold water to cool.
Meanwhile, in 1 1/2-quart glass bowl, layer broccoli, 1/4 cup of the salad dressing, yellow bell pepper, cooked beets, green bell pepper, onion and quartered artichoke hearts. Top with cheese. Cover; refrigerate 4 hours or overnight.
Just before serving, top with remaining 1/2 cup salad dressing. To serve, use long-handled serving spoons to reach all layers.
