New trends in prepared-meal delivery offer healthy, gourmet options fit for any appetite.

What's for lunch? Whatever it is, for most people, it comes from a to-go box. The same goes for breakfast and dinner;a home-cooked meal is simply a rare luxury for many busy Americans.

Add to the mix the constant diet craze and the fact that 57 percent of consumers would use delivery to their home or office if more restaurants offered it, and you've got the recipe behind the rapidly growing $800 million diet-food, home delivery market.
