Consider the bread

The bread is the vehicle on the sandwich highway from plate to mouth.

• Softer, thinner bread is generally better for softer fillings like cheese, avocado, or anything that can be bitten through easily.
• The more you pile things up, the sturdier the bread will need to be so things don't get soggy and fall apart.
• Strong sourdough bread can be good for a sandwich that needs an acidity that's not upfront.
• A heavily seeded wheat loaf works if you need more texture, though not crunch.
