Food for wise man going around America (7)
I believe the answer is:
sausage
'food' is the definition.
(sausage is a kind of food)
'wise man going around america' is the wordplay.
'wise man' becomes 'sage' (sage is a kind of wise man).
'going around' is an insertion indicator.
'america' becomes 'usa' (synonyms).
'sage' going around 'usa' is 'SAUSAGE'.
'for' acts as a link.
(Other definitions for sausage that I've seen before include "Assuage (anag.)" , "... tube-shaped case of minced pork" , "Minced meat product" , "Eg, salami or pepperoni" , "E.g. salami, bratwurst" .)
