Bread's regularly provided with the woman's slice of bacon (6)
I believe the answer is:
rasher
'slice of bacon' is the definition.
(I've seen this before)
'bread's regularly provided with the woman's' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'provided with' is a charade indicator (letters next to each other).
'the woman' becomes 'sher' ().
The alternating letters of 'bread' are 'ra'.
'ra'+'sher'='RASHER'
(Other definitions for rasher that I've seen before include "food cooked in fat?" , "Thin strip of bacon" , "pig, to an extent" , "Slice of meat - more reckless" , "bit of a pig" .)
