I say this because I want to be sure that my offering this picture and information is not misconstrued as saying this food is common in Japan in any way, but it is, nonetheless, being marketed by convenience store "Family Mart". The item pictured above is a curry which features bacon, sausage and lunch meat. As a serving suggestion, crushed potato chips are placed on top of it. The information on the left tells you that the chips are not included, but this curry dish is only 530 yen ($5.30), so you can probably afford to buy a bag of chips for 100 yen ($1.00) and perform a do-it-yourself garnish.
I had to search a little hard to find out how many calories are in this. Without the chips, it's 1400 calories, so this is really good if you plan on skipping dinner or have to run a marathon.
