Sandwiches are classic, but if you want to skip the bread, leafy greens make a great handheld meal. You just have to be careful which kind you choose.
It cost $3.89 from my local Burger King in Brooklyn, New York, and was 310 calories. The classic wrap comes with a large chicken tender, lettuce, tomato, and Royal sauce in a white tortilla.
Lettuce wraps are not only good for you ... any errant bits (just like you would want to use if you were swapping a burger bun out for lettuce), but is still able to wrap nice and tight.
