Prep the bread by slicing 18 slices into the loaf only cutting about 3/4 of the way through. Do not cut all the way through.
Brush mustard in between every other slice.
In each slice of ham, add two slices of Swiss cheese and a pickle.
Tuck the ham, cheese, and pickle in each bread cut where the mustard is brushed.
You should have the Cuban sandwich ingredients in between two slices of bread, so every other bread cut.

Notes
Don't add any condiments.This is also perfect because everyone I know likes to add their own condiments, in their own amounts, and in their own sequence. Just keep the condiments in separate storage containers and allow everyone to self-serve.
Make different types of subs.If you are using meats, make sandwiches with single meats and a few with multiple different meat combinations. You should do that with the cheeses as well.
Leave off the toppings too.Lettuce, tomatoes, and onions all have moisture in them that will make the bread soggy and we are trying to avoid this. Tomatoes are juicy, lettuce wilts and can get warm, and onions are strong and might stink up the sandwiches.
Wrap the sandwiches tight.Whether you wrap them in a large foil package for the grill or oven, or if you wrap them individually for easier serving, wrapping them keeps them fresh and dry!
