We have the new Signature Craft sandwiches at the store I work at. One has pico de gallo, guacamole, and ranch on it; one has dijon mustard, maple bacon, and grilled onions; and one has grilled onions, crispy onions, and Vidalia BBQ sauce. All three can be made with grilled chicken, crispy chicken, or quarter pounder meat.
Honestly, for McDonald's they're not bad. They're like $7 a pop but they're definitely a cut above usual McDonald's fare. Only frustrating part is that it adds like, ten things to the already overcrowded sandwich line...
