Get your ingredients together, I prefer Co-op's own brand of cheese squares. Here I used ready salted crisps, but use your own preferred choice of crisp, beef is particularly good.

Arrange the cheese squares on the bread, one to the top of one side, one to the bottom. Putting them on the separate slices like this holds the crisps in the sandwich better.

Tip the full packet of chips into one slice of bread. Arrange it so all the slice is covered.

Crush lightly the two slices together to break the crisps up a little and press them into the bread and cheese so. As you can see from the photo most of the crisps have stayed in the sandwich.
