'dish' is the definition.
(I've seen this before)

'recipe let it be' is the wordplay.
'recipe' becomes 'r' (abbreviation in medical prescriptions).
'let it be' becomes 'amen' ('amen' means 'let it be' or 'so be it').
'r'+'amen'='RAMEN'

'for wagamama' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for ramen that I've seen before include "Quick-cooking noodles" , "Exotic dish" , "soup" , "Oriental noodles" .)
