Instructions

1. Place tofu, in a single layer, in a large glass or ceramic dish. Whisk tamari, sugar, mustard powder, onion flakes and garlic powder together in a jug.
2. Pour over tofu. Cover with plastic wrap and place in the fridge for 4 hours or overnight to marinate.
3. Preheat a barbecue flat plate on medium-high. Brush barbecue with oil. Cook tofu for 3 minutes each side or until caramelised. Transfer tofu to a serving platter and top with shallots. Sprinkle sesame seeds and dried chilli flakes over and serve hot with extra chilli flakes on the side.
