1. Place the tofu, kelp powder, salt, egg replacer, ginger, soy sauce, onions and sesame oil in a food processor and blend into a paste.
2. Cut each slice of bread diagonally into 2 triangles. Spread the paste on the bread, making a slight mound in the center. Put the sesame seeds on a plate and press the paste side of each triangle into the seeds.
3. Heat the oil to a medium heat and deep-fry the toasts paste side down for 2 to 3 minutes then turn them over and fry until they are golden brown.
4. Remove from the oil and drain on paper kitchen towel. Serve immediately with sweet chili sauce.
Use bread that is not fresh as it will absorb less oil. Also, the tofu can be substituted with the same quantity of mock prawn meat if you're lucky enough to live near an Asian grocer that sells it.
