Notes
You can cook everything in advance. Toast the bread and assemble it before your guests or date arrives. Depending on your timing, you can serve this appetizer hot or cold. To keep the bread crisp, don’t assemble until you’re ready to serve. You can make these vegetarian by swapping the steak for mushrooms or eggplant.
