OAK BROOK, Ill. - McDonald??s took on Starbucks with its McCafé product line, and now the burger chain has its sights set on Subway, Advertising Age reports. McDonald??s will soon roll out its McWrap sandwich nationally, coupled with a big national marketing campaign.

The McWrap, available in some locations currently, has been called McDonald??s "Subway buster." The sandwich is the likely to be the first salvo in its attempt to grab more of the sandwich pie.

Now that its McCafe line has been successful, McDonald??s wants to shore up its sandwich category. The chain sees rivals Chick-fil-A, KFC and Subway has having a strong presence in sandwiches, and will use the McWrap launch as a way to garner more interest in its own sandwiches.

The McWrap has grilled or crisp chicken, cucumbers and romaine lettuce, plus three sauces from which to choose. McDonald??s is banking on the customization and perceived healthfulness of the McWrap as spurring sales. While the chain has snack wraps, the McWrap is larger and had a very successful Chicago test last year.
