End of working week - almost ready - behold meat in sauce (9)
I believe the answer is:
fricassee
'meat in sauce' is the definition.
(type of meat stew)
'end of working week almost ready behold' is the wordplay.
'end of working week' becomes 'Fri' (Friday).
'almost' means to remove the last letter (most of the word but not all of it).
'ready' becomes 'cash' (ready can informally mean cash).
'behold' becomes 'see' (I've seen this in another clue).
'cash' with its last letter taken off is 'cas'.
'fri'+'cas'+'see'='FRICASSEE'
(Other definitions for fricassee that I've seen before include "Dish of fried meat in thick sauce" , "Stew of meat in thick white sauce" , "Dish of meat served in a thick white sauce" , "Meat/veg stew, white sauce" , "eat this?" .)
