Get rid of - sling out - the stodgy food (9)

'stodgy food' is the definition.
'dumplings' can be an answer for 'food' (dumplings is a kind of food). I'm not certain of the 'stodgy' bit.

'get rid of sling out' is the wordplay.
'get rid of' becomes 'dump' (dumping is a kind of getting rid of).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'sling' anagrammed gives 'lings'.
'dump'+'lings'='DUMPLINGS'

'the' acts as a link.

Can you help me to learn more?
