Dish right with garlic sauce, very filling (7)
I believe the answer is:
ravioli
'dish' is the definition.
(I've seen this before)
'right with garlic sauce very filling' is the wordplay.
'right' becomes 'r' (common abbreviation).
'with' says to put letters next to each other.
'garlic sauce' becomes 'aioli' (synonyms).
'very' becomes 'v' (common abbreviation).
'filling' is an insertion indicator.
'aioli' enclosing 'v' is 'avioli'.
'r'+'avioli'='RAVIOLI'
(Other definitions for ravioli that I've seen before include "Italian pillow-shaped pasta" , "Meat-filled pasta squares" , "Small square pasta cases containing savoury filling" , "Pasta with savoury stuffing" , "Filled type of pasta" .)
