Prepare all ingredients necessary to create your spider sandwich.
Start off with the base - by taking 2 slices of bread and cutting 2 equal circles from them.
Slice the tomato and 6 triangle-shaped spider legs from cheddar cheese.
Assemble! Place one slice of bread on a plate. Then arrange the tomato and lettuce on top, and the cheddar "legs" along the outer corners of the sandwich. Carefully position the second slice of bread on top and stick 2 green olives for eyes using toothpicks. Note: Make sure to remove the toothpicks before serving to a child
