Putting on these vegetables (6)
I believe the answer is:
greens
I believe this is a double definition.
'putting on these' is the first definition.
(I've seen this before)
'vegetables' is the second definition.
(green is a kind of vegetable)
(Other definitions for greens that I've seen before include "Vegetables and politicians of a certain hue" , "Signs people should go" , "They're for putting on - vegetables" , "Ecology party" , "Leaves" .)
