- The Potluck is a two-tiered casserole tote with an insulated compartment to carry warm or cold items and a separate zippered entry section on top that can be used for shelf-stable foods, utensils, and the like. Handles at the back have built-in elastic loops to one large serving utensil. A framed window slot and ID card will help to ensure your Potluck will make its way back to your kitchen.
