The contrast between the crunchy seeds and vegetables and the rich, savoury sauce is what makes this dish so delicious. Serve it solo, or with rice or noodles.
Heat the oil in a wok or large frying pan. Add the seeds. Toss over a medium heat for 1 minute, then add the garlic and ginger and continue to stir-fry until the ginger is aromatic and the garlic is golden. Do not let the garlic burn or it will taste bitter.
