The more things change, the more they stay the same. Take the sandwich, for example, which has long reigned as America’s preferred lunch on the go. Breathing new life into the classic concept, Wonder Bread has this month rolled out the Sandwich Wonder-izer at www.wonderbread.com/#/nutrition/sandwich_builder.

The new online tool enables consumers to create unique sandwich combinations from a list of over 120 ingredients, including everything from cheddar cheese to cucumbers, and sprouts to salami, while calculating the sandwich’s nutrition values in real time with each added ingredient. According to the iconic product line, a division of Irving Texas-based Hostess Brands, Inc., the Sandwich Wonder-izer can create billions of sandwiches and simultaneously offer users guidance on how to get the daily recommended amounts of key vitamins and minerals.

Sandwiches dreamed up from scratch can be given names and shared online with friends through such social media sites as Facebook and Twitter. As well as facilitating the creation of new sandwiches, the tool provides a menu of pre-made sandwich recipes, among them an Elvis Presley-inspired banana-and-peanut-butter combo and better-for-you choices featuring vegetables. The Sandwich Wonder-izer can additionally recommend ingredients to increase the amount of calcium, fiber, iron and protein in a given sandwich.

According to Stephany Verstraete, VP of marketing for Wonder Bread: “The Sandwich Wonder-izer is a fun and easy-to-use tool that not only builds delicious and nutritious sandwiches, but also provides an excellent opportunity to teach family members of all ages about the importance of getting enough vitamins and minerals in our diets.”

In addition to bringing the venerable craft of sandwich-making firmly into the Internet age, the tool transforms the chore of preparing lunch to tote to school or work into an entertaining, shared enterprise, with a an eye on ways to make lunches healthier. With a promotion as clever as this, consumers should be eager to bite.
