Drop in network, second for satellite dish (7)
I believe the answer is:
lasagna
'satellite dish' is the definition.
'lasagna' can be an answer for 'dish' (lasagna is a kind of dish). I am not sure about the 'satellite' bit.
'drop in network second' is the wordplay.
'drop' becomes 'sag' (sagging is a kind of dropping).
'in' is an insertion indicator.
'network second' becomes 'lana' (I am not sure about this - if you are sure you should believe this answer much more).
'sag' going into 'lana' is 'LASAGNA'.
'for' is the link.
Can you help me to learn more?
(Other definitions for lasagna that I've seen before include "Italian cooking" , "Calorie-rich food" , "Broad flat pasta" , "Italian dish" , "pasta's provided" .)
