Now, be gentle if working around the centre of satellite dish (4,10)
I believe the answer is:
beef wellington
'dish' is the definition.
(beef Wellington is a kind of dish)
'now be gentle if working around the centre of satellite' is the wordplay.
'working' is an anagram indicator.
'around' means one lot of letters goes inside another.
'the centre of' indicates the central letters.
The middle letter of 'satellite' is 'l'.
'now'+'be'+'gentle'+'if'='nowbegentleif'
'nowbegentleif' with letters rearranged gives 'beefwelington'.
'beefwelington' placed around 'l' is 'BEEF WELLINGTON'.
(Other definitions for beef wellington that I've seen before include "meat dish" , "meal" , "dish - with 10a" , "Meat-in-pastry dish" , "Menu item" .)
