At each Ootoya store (excluding some stores), "Furusato Ouchi Rice-Beef and Taro Miso Boiled Set Meal-" is on sale. The price is 960 yen for a single item and 1,150 yen for a set meal (both include tax).
This is Imoni, which is popular in the Tohoku region and is perfect for the cold season. It is made with soup stock that is combined with the slightly sweet Sendai miso, and taro, plenty of mushrooms, green onions, Chinese cabbage, and konjac are added to a generous amount of beef to make a hot pot with plenty of ingredients.
The set meal includes "burdock and okaka ginger rice," which has the flavor of ginger, spicy eggplant mixed with doubanjiang, and a small bowl of spinach.
