No, its not one of those sex positions with an urban name. Its a sandwich that I learned from an officemate in Funabashi, Chiba. It mainly consists of ingredients which you can get at your friendly neighborhood 100 yen 'combini' (convenience store). And let's face it, when you're living in the most expensive metropolitan area, those 100 yen stores are gonna be your new best friend.
The "Spicy Kinoshita" basically contains bread, veggies (in this case, lettuce), mayo, mixed pepper spices and meat (preferably cold cuts)
For this instance, we grab some generic Japanese Mayonnaise, bread, mixed spices, a head of lettuce and 'Bits Weiner' from Lawson 100 Yen store. Total cash out: 525 yen. Almost the same price as a meal at Hotto Motto, but, with the quantity you have, it would tide you over for at least 3 meals... that's at least 1000 yen saved from most common take-out joints in Tokyo metropolitan... or Chiba in this case.
First, layout clumps of mayo (with the generic bottle, it won't be a problem) then sprinkle the mixed spices. Put in the cold cut then top with lettuce. Its that simple. The taste, is like having a light salad in a sandwich. Its not that heavy on the tummy but enough to satisfy your hunger.
