Wandermeal

This tough, dried cake is a halfling invention made from flour, water, and spices. Wandermeal keeps for months without spoiling, travels well, and fills the belly. However, eating it for over a week without other nutrients requires the eater to make a daily Fortitude saving throw (DC 15 + 1 for each additional day) or be sickened. The effect ends 1 day after more nutritious food is eaten. The listed price is for a day's worth of food.
