it's appeared in my neighbours veggie box so we are intriged to know what it is

[arugula]

Nearly everything else in the picture looks like nasturtium. Could they be the outer seed pods?

Edible, seeds and flowers if it is.

[mumofstig]

don't think they're nasturium seed pods IIRC

maybe radish seed pods 

[mrs mud]

it's hard to see in the pic but it's growing on it's own in one of the box compartments that my neighbour uses, but she can't remember what she planted in that bit

everything she planted was veg/herbs but there are lots of ordinary plants just outside of it

here's another pic

My money is on radish too 

I leave some to make some seeds heads every year as they are so nice to munch

Radish- very nice in salads- but do have a bit of a kick!!

I grew some for the pods this year- Munchen Bier, are specifically bred for the seed pods!

my radishes look like that too very nice to nibble 1st time i've tried them, good use for the ones that don't bulb up.

I'd say it's munchen bier.  Acquired taste
