Pre-heat oven to 180C
Peel and chop your veggies (carrots, parsnips, onion)
Layer root veggies into a roasting dish
Add olive oil, rosemary, garlic powder & salt/pepper to root veggie mix
Stir veggie mix to coat with oil/garlic mix
Place veggies in pre-heated oven for about 40 minutes
Meanwhile, rinse pearl barley well
Add pearl barley to a pot, adding in your stock
Bring pearl barley to a boil - cook at boil for 10 minutes
After 10 minutes, turn pearl barley down to a simmer for 20-30 minutes
When there's 10 minutes left on the pearl barley, add your broccoli into the veggie mix in the oven (it's been in for 30 minutes)
Let the veggie mix & pearl barley cook for a final 10 minutes
The pearl barley is done when it's soft but still a little bit chewy
