The sandwiches were made available starting this week on Monday.
The Red Bell Pepper Grilled Chicken Sandwich gains it namesake from a roasted red bell pepper sauce and is served simply with lettuce and cheddar cheese.
The Basil Grilled Chicken Sandwich features a basil pesto with lettuce, tomatoes, and a mayo-mustard blend.
Basil pesto and, particularly, the roasted red bell pepper sauce are fairly unusual for fast food chains. It seems like something that might fare well here in the US.
Both sandwiches carry a price of 420 yen (~$4.11 US) a piece and will be available through May 25, 2014.
