1. Preheat the oven to 200°C (180°C with fan) Gas mark 6. Scatter a lined baking tray with the courgette and red onion and sprinkle with the vegetable oil and the black pepper. Give the vegetables a shake to coat them evenly. Bake until golden and cooked. Set aside.
2. Meanwhile, place the pearl barley and stock cube in a large saucepan and cover with 1 litre of cold water. Bring to the boil until all the water has evaporated and the barley is soft and cooked. Remove from the heat.
3. Pour the Carnation® Light Evaporated Milk into the barley, add the crushed garlic clove and Parmesan and stir well. Fold through the roasted vegetables and then return to the hob to heat through.
