Take one slice of whole wheat bread and spread half of the hummus and tapenade mixture on it (you can omit the tapenade if desired).
Repeat the process with the second slice of bread, spreading the remaining hummus and tapenade mixture on it.
Layer the thinly sliced 1/4 cucumber and the coarsely grated 1 carrot on top of the hummus and tapenade on one of the bread slices.
Combine both slices to form a single sandwich.
This recipe yields one delicious sandwich packed with the mentioned ingredients.
