I've always turned to collard greens when preparing healthy "sandwiches" for myself and others; they were a favorite offering in my healthy, to-go foods line. 

Collard greens are an excellent source of vitamin K, vitamin A, manganese, vitamin C, dietary fiber, calcium, vitamin B1, vitamin B6 and iron. They also provide the fourth greatest amount of antioxidants behind sweet potato greens, mustard greens and kale.

Substitute collards for bread or your traditional wrap, and you'll most likely feel lighter, healthier, and became leaner. I've watched people lose 10-20 lbs. from simply making the swap.  Anything you have in your fridge can be wrapped inside and made into an easy, to-go meal.
