Preheat the oven to 200°C/180°C fan/gas 6. Put the broccoli on baking trays, drizzle with oil and season with salt. Roast for 30 mins. Meanwhile, bring a pan of water to the boil, add the pearl barley and cook for 20 mins; drain and set aside.

Melt the butter in a large pan and add the shallots. Cook for 8-10 mins, stirring often, until softened. Reduce the heat, stir in the garlic and cook for 2-3 mins. Stir in the flour and cook until the flour smells biscuity.

Increase the heat and add a little milk, stirring; the mixture will stiffen. Gradually add the rest of the milk, stirring, to create a thick white sauce. Remove from the heat; stir in the mustard, 200g of the cheese and salt to taste.
