Split the sandwich thin, and using a small circle cutter, cut and remove a semi-circle ‘ear’ from each side of the bottom slice.

Butter and fill the sandwich with a filling of your choice, turning the ear pieces over and popping them into the gaps in the sandwich as you do so. I buttered mine and added a slice of ham to fill it. Other sandwich meats such as roast beef or chicken, or a slice of cheddar cheese would also work well for a neat and tidy sandwich!

Using a circle cutter with a similar diameter to the width of the sandwich thin, cut out a semi-circle from a slice of cheddar cheese and place it so that it covers the bottom half of the sandwich.

Take the small circle cutter and cut out two circles from the remaining cheese, popping them in place for the eyes. Top the cheese ‘eyes' with the blueberries.

Take the slice of carrot, and using the small circle cutter, cut out a thin crescent for the mouth. Pop the carrot mouth onto the sandwich to finish it.
