For best results use the KitchenAid® Food Processor.
Place the barley into a microwave safe bowl, cover with boiling water. Cover with plastic wrap and cook 10 minutes on high or until the water is absorbed and the barley is par-cooked.
Meanwhile, attach the thick slicing disc to the food processor. With the motor running add the garlic, onion, celery and carrots. Remove from the bowl.
Heat the oil in a large saucepan, add the sliced vegetables and saute 8 minutes. Re-attach the slicing disc and cover. Start the processor and add the parsnips, potatoes and broccoli. Remove and set aside.
Add the stock, par-cooked barley, parsnips and potatoes to the sauteed softened onion mixture. Bring to the boil and simmer uncovered for 20 minutes or until all vegetables are just tender.
Add the tomatoes, broccoli and season well with salt and pepper. Cover and cook about 7 minutes or until broccoli is just tender. Stir in fresh herbs just before serving.
