Mild-flavored onion (7)
I believe the answer is:
shallot
'mild-flavored onion' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shallot that I've seen before include "bit of salad" , "Rowing boat" , "Type of onion" , "One may get into a stew" , "Edible onion-like bulb" .)
