For the cauliflower........cut into small florets then boil until tender. Drain and allow to dry. Heat some oil in a pan, then add cumin and coriander seeds until they crackle. Now chuck your cauli back in and stir fry until hot. finish with a big pinch of salt.
The secret to getting lovely crispy and non-greasy poppadoms is to get your oil really hot before you throw them in the pan. then they are in the oil for the minimum time.
