Final answer:
Mrs. Peters' reference to 'bread set' in a play or literary work suggests bread dough left to rise, typically seen in older settings.
A 'grown-up grilled cheese' is usually made with artisan bread like sourdough, whole grain, or rye, depending on the historical context of the work.
Step-by-step explanation:
The question posed appears to be referring to a scene from a play or literature piece, rather than a factual inquiry about types of bread used in sandwich preparation. Therefore, answering the question 'What bread is the grown-up grilled cheese served on?' requires some interpretation from the context provided by the excerpt.
Mrs. Peters refers to 'bread set' on a table, which in an old-fashioned or historic setting, particularly in plays or stories, suggests that bread dough was prepared and left out to rise. In the context of grilled cheese, a 'grown-up grilled cheese' is often made with more sophisticated ingredients than the classic white bread and American cheese.
It could be served on a variety of artisan bread such as sourdough, whole grain, French baguette, or a hearty rye bread, depending on the setting and time period of the literature.
The grown-up grilled cheese is typically served on a variety of breads, depending on personal preference and regional variations.
Some common bread choices include sourdough, ciabatta, rustic country bread, or whole wheat. The choice of bread can greatly impact the flavor and texture of the grilled cheese sandwich. For example, sourdough bread adds a tangy flavor and a crispy crust, while ciabatta has a chewy texture that complements the melted cheese.
