Tahini Lentils

In a jug, mix the tahini with the zest and juice of the lemon and 50ml of cold water to make a runny dressing. Season to taste, then set aside. Heat the oil in a wok or large frying pan over a medium-high heat. Add the red onion, along with a pinch of salt, and fry for 2 mins until starting to soften and colour. Add the garlic, pepper, green beans and courgette and fry for 5 min, stirring frequently. Tip in the kale, lentils and the tahini dressing. Keep the pan on the heat for a couple of mins, stirring everything together until the kale is wilted and it’s all coated in the creamy dressing.
