Red beans and ... fries?!?

I stopped off at my semi-local Wendy`s today, in the mood for a treat from the motherland (Actually I went there cause you can get a variety of burgers for about $1 CAN) and I noticed a rather inconspicous sign on the table, advertising an seemingly innocent looking "hamburger". The text on the sign read something as follows: "Instead of meat, we`ve added delicious sweet red bean paste". Once I was done with all of the dry heaving and fainting spells, I came to realize that Japan truly is the land where East meets West.
