With sauce, enjoy it (6)
I believe the answer is:
relish
'with sauce' is the definition.
'relish' can be an answer for 'sauce' (I've seen this before). I'm not sure about the 'with' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for relish that I've seen before include "what might add flavour" , "Salsa, chutney etc" , "Enjoy greatly - such sauce!" , "'Take pleasure in, savour (6)'" , "Savour; an appetiser" .)
