Preheat your oven to 220C (200C fan).
Get your aubergine and spike it several times with a fork. Brush with vegetable oil and then roast for 40 minutes or until the skin is wrinkly and the middle is soft.
Remove your aubergine from the oven and leave to cool for 5 minutes. Then, remove the skin and mash with your garlic, sugar, soy sauce, salt, black pepper, and crushed nori sheet in a bowl. Give everything a good mix and then cover and leave for at least 4 hours in the fridge, preferably overnight.
The next day, slice 8 pieces of bread into squares. Remove the crusts (make breadcrumbs out of them!), and set them aside.
Get your aubergine "prawn" filling from the fridge and give it another good mix.
Lay one piece of square bread down. Coat a 2 cm layer of your aubergine filling (¼ of the filling) onto the piece of bread and top with another piece of bread. Repeat this step for all of your vegan prawn toasts.
In a shallow bowl or on a plate, combine your 2 tablespoon vegetable oil and 2 teaspoon cornstarch/flour until you get a thick vegetable oil mixture.
Gently coat the prawn toast in the vegetable oil mixture by tossing the toast around in it. Then, coat in sesame seeds. Repeat for the 4 vegan prawn toasts.
Place a frying pan on medium heat with a splash of oil. Add in your vegan prawn toast and fry on each side for around 4 minutes or until golden and crispy.
Remove from the pan and set on a piece of kitchen towel to remove any excess oil. Serve up and enjoy!
