Starter of savoury flatbread wraps and Swiss-style fried potato (5)
I believe the answer is:
rosti
'fried potato' is the definition.
(I've seen this before)
'starter of savoury flatbread wraps' is the wordplay.
'starter of' suggests taking the first letters.
'flatbread' becomes 'roti' (type of flatbread).
'wraps' is an insertion indicator (inserted letters get wrapped up).
The initial letter of 'savoury' is 's'.
's' placed into 'roti' is 'ROSTI'.
'and swiss-style' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rosti that I've seen before include "fried potato" , "Potato cake" , "potato dish" .)
