Here is a selection of fruit and veg at my local supermarket this morning. Everything is plastic wrapped. Some items are double wrapped.
'Baby' Pumpkins
Sweet red potatoes
Tomatoes
Onions
Garlic
Assorted Greenery
Chili Peppers
Carrots
Various Mushrooms
Shiitake
and worst of all
Bananas
There is separate section of loose product, but you can guarantee the people on the weigh station are going to wrap it in plastic anyway, so you can't win.
