Chili brand getting revamp, an original idea (10)
I believe the answer is:
brainchild
'an original idea' is the definition.
(I've seen this before)
'chili brand getting revamp' is the wordplay.
'getting' is a charade indicator (letters next to each other).
'revamp' indicates anagramming the letters (I've seen 'revamped' mean this).
'chili'+'brand'='chilibrand'
'chilibrand' with letters rearranged gives 'BRAINCHILD'.
(Other definitions for brainchild that I've seen before include "Invention" , "Bright idea" , "Original idea or work" , "One's original idea" , "wheeze" .)
