Eating outside a home, this is good for starters (9-3)
I believe the answer is:
launching pad
'this is good for starters' is the definition.
The definition suggests a singular noun which matches the answer.
'eating outside a home' is the wordplay.
'eating' becomes 'lunching' (lunching is a kind of eating).
'outside' means one lot of letters goes inside another.
'home' becomes 'pad' (pad can mean someone's home).
'lunching' placed around 'a' is 'launching'.
'launching'+'pad'='LAUNCHING-PAD'
Can you help me to learn more?
(Other definitions for launching pad that I've seen before include "spot of rocket" , "Rocket platform" .)
