IRVING, TEXAS — Hostess Brands has gone “mobile” with the launch of the Sandwich “Wonder-izer” application, a free app for the iPhone and iTouch that enables consumers to create unique sandwich combinations from a list of more than 120 ingredients while calculating the sandwich’s nutrition values in real time with each added ingredient. “As our culture becomes increasingly mobile, The Sandwich Wonder-izer app is a fun and engaging tool that families can use to learn about making healthy food choices while creating delicious, nutritious sandwiches,” said Stephany Verstraete, vice-president of marketing for Wonder Bread.
