Sweet potato and barley pilaf

Method

1. Peel the sweet potatoes and cut into 1.5cm dice. Heat 3 tbsp oil in a large frying pan over a medium-high heat. Fry the diced potatoes for 15 minutes, tossing occasionally, until soft and golden. Put on a plate.
2. Finely chop the onion and garlic. Put a glug of oil in the pan over a low heat, then add the onion and garlic and cook for 8 minutes until soft. Turn the heat to medium and add the barley. Stir to coat, cook for 3 minutes until it smells nutty, then add the stock. Season and cook for 15 minutes until the barley is cooked but still has some bite.
3. Finely chop the basil and mix with the zest and juice of the lemon and a drizzle of oil. Season and set aside. Add the sweet potatoes to the pilaf then, after 1 minute, add the spinach and cook until wilted. Season and serve with the basil oil and crumbled cheese.
