1. The Bread – This is key. It’s what binds the whole sandwich together. It can be store-bought Wonder-bread (appropriate in certain situations) or it can be a home-made sourdough, but it must be chosen with care and with the end result in mind.
2. The Spread – Here we’re talking mayo and mustard, or if you’re feeling fancy, pesto or red pepper spread. This acts as a moisture barrier between the bread and the fixings so that the bread doesn’t get too soggy too quickly.
3. The Main Ingredient – This is the main focus of the sandwich and what is providing the real sustenance. Whether it’s heirloom tomatoes or leftover roast chicken, this is the whole reason why you started craving the sandwich in the first place.
4. The Secondary Ingredients – These are the supporting actors of your sandwich and aren’t meant to take center stage. Instead, they add texture and flavor contrast to the main ingredient. They can be lettuce, tomatoes, sprouts, or a slice of good cheese.
