Execution
Follow the master commands
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.
