Quizno’s, Schlotzky’s, other deli shops and just about every casual Tex-Mex restaurant use some kind of basket and liner to serve food to their customers. They are sturdy, produce slightly less waste, and don’t require as much cleaning – perfect for picnics and outdoor eating. You can find them at restaurant supply stores.
At Acemart in Austin for example, the baskets are $1.05 each and a box of 500 wax paper liners is $8.45. Did I mention they’re great for kids?
