RE: Display Warmer - Humidified?
Hard to say whats available in your area food (pre-packaged). Check with some of your local food wholesalers. Maybe also contact some of these Mfg. companies and see if they will let you use one of their refridgerated display units for selling their products. (Like Coke and Pepsi do with theirs). Also look on Ebay for Merchandisers, may find a good deal on something your looking for. If you had the space for a stainless steel table, meat slicer, fridge and a 3 bay sink, you'd be on the way to making your own sandwiches!
