Consider doing your book report on a cookbook about making sandwiches. Find some cookbooks that describe sandwich making geared to young people. Cookbooks are ideal for book reports involving a discussion of sandwich styles, because cookbooks either focus on one style, a group of related styles, or divide a variety of different sandwich styles into separate categories. Consider a book such as Super Sandwiches: Wrap'em, Stack'em, Stuff'em by Rose Dunnington; Sandwiches and Snacks by Susannah Blake; or Grilled Pizza Sandwich and other Vegetarian Recipes by Kristi Johnson for your book report.
For book reports on sandwich styles at the high school or college level, choose a sandwich cookbook other than those written specifically for children. Choose a particular type of sandwich style cookbook for your report. Some possibilities include American Sandwich by Becky Mercuri; Simple Italian Sandwiches by Jason Denton with Kathryn Kellinger; or Tastefully Small Finger Sandwiches: Easy Party Sandwiches for All Occasions by Kim Hendrickson.
Cheese makes a popular sandwich style among children's books about sandwiches. Combine learning about cheese sandwich styles with reading such books as Hamster and Cheese by Colleen A.F. Venable; and Cat & Dog Make the Best, Biggest, Most Wonderful Cheese Sandwich by Kimberlee Graves.
Pick a book for your report on sandwich styles that involves mystery, adventure or intrigue. For this kind of a sandwich style book report, choose The Curse of the Bologna Sandwich by Greg Trine; Mystery at the Club Sandwich by Doug Cushman; or Another Dirt Sandwich: Some Rambling and Hilarious Exploits of Tbyrd Fearlessness by Ray Friesen.
Write a book report on a book about quirky styles of sandwich. For example, the book Carla's Sandwich by D. Herman deals with a character whose peculiar sandwich tastes help her befriend the school bully. The vintage children's book The Giant Jam Sandwich by John Vernon Lord with Janet Burroway deals with a town that uses a giant jam sandwich to capture wasps that have invaded the community.
