Since 1983, this fast-food sandwich chain has been growing in popularity and success in its quest to be in a "position of power in a worldwide sandwich empire." Jimmy John's has a focus on wholesome ingredients such as meats without fillers, real mayonnaise and olive oil. The chain bakes its own bread and slices and prepares meat and vegetable ingredients in-house every day. Although the ingredients may be wholesome, it's still important to keep an eye on calories and fat, as those sandwich fixings can add up fast! Here are some tips for navigating the menu during your next Jimmy John's visit.
