Put the barley, quinoa or freekeh in a medium saucepan with 320ml (11fl oz/1¹⁄³ cups) water, place over a high heat and bring to the boil. Reduce the heat to medium and simmer for 20–25 minutes (10–15 for quinoa) or until tender and the liquid is absorbed. Remove from the heat and set aside to cool.
Squeeze the kimchi to remove the excess liquid, reserving the liquid in a small bowl.
To make a dressing, place the vinegar, olive oil and two tbsp of the reserved kimchi liquid in a small bowl, season to taste with salt and pepper and stir to combine.
Place the kimchi, mangetout, sugar snap peas, edamame, courgette and cooked grain into a large mixing bowl. Add the coriander and dressing and gently toss together.
