Whisk egg
with milk and salt. Melt the butter, stir fry eggs until cooked and
mash. Slightly fry the cocktail sausages. Cut the upper part of butter
roll horizontally, scoop out the inside. Add the fried egg. Stick the
sausage, put on black sesame seeds as eyes. In the front of the roll,
make a cut but don't cut through. Put a little piece of roll crust to
make the windscreen of the car. Cut the sausages to make the wheels. Use
mayonnaise to stick on the sides. Serve immediately.
