Pour the light olive oil into a smallish saucepan. The oil should only fill the pan a third. Heat on a medium to hot setting, my hob goes to 9 and I set it at 7.
In a large flat dish or plate, put the cornflour, spices and salt and pepper. Mix well.
Drain the tofu, rinse and pat dry.
On a chopping board, with the tofu flat, slice through horizontally. Then cut into evenly sized cubes. I cut 5 slices on the larger side and 4 across giving me two layers of 20 cubes, 40 in total.
Separating the cubes put them all into the cornflour mix and coat well. Don't worry if it looks a bit wet and sticky.
Fry in batches of about 10 pieces at a time. They should be gloden brown and bobbing on the surface. Once cooked transfer to a warm serving dish.
Mix the dipping sauce ingredients, stirring well to a smooth paste.
Serve with the Chinese style greens.
An optional extra is to stir some lightly fried spring onions, crushed black pepper, garlic and fresh chopped chilli into the tofu for extra kick.
