Chop the prawns with a knife or you can also use a food processor.
In a bowl, mix all of the ingredients for the prawn paste, till you get a well mixed sticky paste.
I like leaving the crust on for the toast for added crunch but feel free to trim it off if you wish.
Roughly divide the paste into 4 equal parts. Spread one portion onto a piece of toast, right to the edges.
Put sesame seeds onto a flat plate. With the shrimp paste side down, place the toast over. Gently press with your fingers to ensure sesame seeds are firmly stuck to the paste. Repeat to finish all pieces.
Cut each piece of toast twice diagonally into 4 triangles.
Heat up oil in a pan over medium heat. When the oil is hot enough, put in the triangle pieces with the sesame seed side facing down. Flip over when the first side becomes golden. When the other side browns, remove it from the pan and drain on some paper towel
If you prefer to air-fry, preheat the air fryer at 200°C for 3 mins. Brush a thin layer of oil over both sides of the toast. When the air fryer is ready. Place in a single layer over the crisper tray with the sesame side facing up. Cook for around 3-4 mins until it browns.
