Royal is only getting this type of food (7)
I believe the answer is:
rissole
'type of food' is the definition.
'royal is only getting' is the wordplay.
'royal' becomes 'r' (common abbreviation e.g. RM - Royal Marine).
'only' becomes 'sole' (synonyms).
'getting' says to put letters next to each other.
'r'+'is'+'sole'='RISSOLE'
'this' is the link.
(Other definitions for rissole that I've seen before include "Croquette" , "Sil rose for the meatball" , "Fried meat dish" , "Fried meat/breadcrumb ball" , "Small pastry" .)
