Step 1: Butter your bread as you would usually.
Step 2: Simple break up your digestives into smaller pieces (but not too much otherwise theres no crunch, just enough so they fit in one half of the piece of bread)
Step 3: Fold the bread over the chocolate digestives + enjoy
Step 5: Obviously works just as well with 2 slices of bread + that way you can fit more biscuits in, but i prefer the folding method as im cheap + this way saves bread.
Step 7: Also good in toasties with cheese.
