A computer-assisted method of determining and producing quantities of perishable, store-prepared food items that should be displayed for consumer selection and purchase on a daily basis is provided. The method includes collecting daily sales data for the perishable, store-prepared food items and saving the daily sales data in memory. For a current specific day of the week, the daily sales data is processed for prior occurrences of the specific day to determine, for each of the perishable, store-prepared food items, a quantity to be placed on display. A total preparation quantity is reported for each of the perishable, store-prepared food items.
