Outside America Herb provides a meat product (7)
I believe the answer is:
sausage
'a meat product' is the definition.
(product typically made of pork)
'outside america herb' is the wordplay.
'outside' means one lot of letters goes inside another (some letters go outside others).
'america' becomes 'usa' (United States of America).
'herb' becomes 'sage' (sage is a kind of herb).
'usa' placed inside 'sage' is 'SAUSAGE'.
'provides' acts as a link.
(Other definitions for sausage that I've seen before include "Seasoned minced meat stuffed in casing" , "Not a - means nothing" , "sort of roll?" , "Tasty tube of meat" , "Minced meat and fat in cylindrical skin" .)
