Ingredients:
1 cucumber
1 small tin of flavoured tuna
1 avocado block cheese (your choice depends on your preference)

How to Prepare:
Quite easy i just thought it up the other day and i haven’t tried it yet but it sort of gives a substitute instead of using cracker biscuits. Slice the cucumber to reasonable thickness. Put a slice of cheese on the cucumber. Then some avocado then finally some flavoured tuna on top
