What is the recommended practice when toasting the sandwich bread?

Toasting only the bread is the recommended practice because it allows the bread to achieve a desirable texture and flavor without affecting the other ingredients' temperature and moisture. When bread is toasted on its own, it becomes crisp and enhances the overall eating experience.

If the meat or other fillings were toasted along with the bread, they could overcook or dry out, detracting from the sandwich's quality. This practice ensures that the bread complements the filling instead of compromising its integrity. Each ingredient in the sandwich has a specific cooking requirement, and toasting the bread separately allows for a balanced and enjoyable sandwich assembly.
