30 Secret Menu Items at Every Fast Food Chain

While most fast food chains seem to offer more options than a person could eat in a lifetime, it's often what doesn't make their menu that holds the most allure. In fact, while your friends are getting the same predictable products at their favorite fast food chain time and time again, you could be eating a bit more adventurously. Enter: secret menu.

From Chipotle to KFC, fast food chains have a wealth of deliciously decadent secret menu items just waiting for customers to say the magic words. Of course, these aren't everyday indulgences. Luckily, our ranking of McDonald's orders can help you pick a healthier fast food meal.

If your usual burrito order just isn't cutting it, try the nachos at Chipotle instead.

Vegetarians, rejoice: salads aren't the only veggie option on McDonald's menu. Just ask for a grilled cheese and most stores will be happy to oblige.

If you can't decide between Chick-fil-A's chicken club and the crispy chicken sandwich, go ahead and combine them. The Fried Chicken Club simply subs in fried chicken for grilled in this off-menu order.
