Green/grocer/ies

What I learned on yesterday's trip to the greengrocer: that offered the first of the English asparagus for £5, and a punnet of Belgian strawberries, also for £5, I don't need to think about it; I'll have the asparagus. There will be other strawberries, but asparagus comes and goes too fast. We shared them at lunch time, six stubby little fingers, boiled for five minutes maximum, bright green and tender, with a nob of butter.

Thinking about posting this, in the middle of the night when your thoughts go off the tracks, I wanted a word for "things you buy at the greengrocer's" and couldn't think of one. You buy groceries at the grocer's, but what do you buy at the greengrocer's? Well, fruit and veg, I suppose (or maybe fruitandveg). And come to think of it, what are groceries, anyway? "the food and supplies sold by a grocer", says Merriam-Webster, which is pretty circular. Are groceries always plural, or can you buy just one grocery? I think a grocery is the shop itself, rather than, say, a single tin of beans...

I fell asleep before I reached any conclusion.
