Dull fare, e.g. peppers, thrown back up (6)

I believe the answer is:
stodge
'dull fare e' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'g peppers thrown back up' is the wordplay.
'peppers' becomes 'dots' (dot can mean to sprinkle or pepper).
'thrown back' says the letters should be written in reverse.
'up' becomes 'e' (I can't explain this - if you can you should give a lot more credence to this answer).
'g'+'dots'='gdots'
'gdots' reversed gives 'stodg'.
'stodg'+'e'='STODGE'
Can you help me to learn more?
(Other definitions for stodge that I've seen before include "Heavy and indigestible food" , "Heavy meal" , "heavy fare" , "Indigestible or dull food" , "treacle pudding?" .)
