Step 2Meanwhile, make the toasted seeds. Add all the seeds, oil, sugar and a good pinch of sea salt, and cook for 2-3 minutes, tossing everything together as the seeds toast, until they are fragrant and beginning to pop. Step 3To make the dressing, put the tahini in a small bowl with the garlic, lemon juice and lemon zest, yogurt, honey and oil. If the dressing is too thick, add a little dash of cold water to loosen. Spoon over the dressing and finish with a scattering of the toasted seeds and mint leaves before serving.
