Stuff in good meat — good for starter (7)
I believe the answer is:
gingham
'stuff' is the definition.
(gingham is a type of material)
'in good meat good for starter' is the wordplay.
'good' becomes 'g' (abbreviation).
'meat' becomes 'ham' (ham is a kind of meat).
'good' becomes 'g' (abbreviation).
'for starter' says to put letters next to each other (some letters go at the start).
'in'+'g'+'ham'='ingham'
'ingham' put after 'g' is 'GINGHAM'.
(Other definitions for gingham that I've seen before include "Cotton cloth, maybe checked" , "Checked material" , "Lightweight cotton fabric" , "Light cotton checked fabric" , "Fabric in a plaid weave" .)
