Lots of foods used for side dishes or appetizers, like French fries, onion rings, chicken strips, and jalapeno poppers are pre-made so that you and your staff can just scoop what you need to fulfill an order. The secret is to keep them warm so that customers don't get cold food. The Hatco line of Heated Shelf Food Warmers, with lamps and/or heated bases, will be sure to maintain cooked food temps so that whatever you serve always stays warm and delicious.
