- Pre-set your oven to 180 degrees Celsius. 
- Get your barley cooking in plenty of salted water- it needs a good 30-40 minutes cooking time (refer to instructions on your pack) to give it a nice chewy, but not too soft texture. 
- While the barley is cooking, put a generous glug of Olive Oil in a roasting tin and add the chopped sweet onion and the whole garlic clove. 
- Pick thyme leaves off 2 or three sprigs and add to the oil- the more herbs the better really. 
- Leave it to cook in the oven for a few minutes to let the thyme and onion flavours infuse the oil, then add the tomato chunks. 
- Roast for about 15-20 minutes, you don’t want it to turn to mush, yet you want that concentration of lovely flavours and juice. 
- Turn off the oven and leave it there with an open door. 
- Once your barley’s cooked, rinse with hot water to stop it from sticking and add some olive oil. 
- Take the tomatoes out of the oven and gradually add the barely to your roasting tin, making sure there’s enough oil and tomato juice to envelop the grains nicely. 
- Season with pepper and salt to taste. I also add some chopped black olives for some extra salty texture. 
- Present it in a beautiful bowl and serve it warm as part of a lunch or Mediterranean dinner, it’s also a perfect picnic dish and accompanies roasted meats beautifully.
