Not easy to do, as a single person, when lettuce comes in a big head that rots before one person can eat it. Radishes often come with the leafy tops attached. Leads to quicker wilting.
I like the way radishes are presented at the Bellingham Grocery Outlet. Topped and chopped from their rat tail like roots. Then washed and packed in an individual size package. Like eating potato chips. A nice snack pack.
Vegetables can be very good and easy to eat when presented this way.
