Feeble sort of meal (4)
I believe the answer is:
'feeble' is the definition.
(lame can mean feeble or pathetic)
'sort of meal' is the wordplay.
'sort of' indicates an anagram.
'meal' is an anagram of 'LAME'.
(Other definitions for lame that I've seen before include "Fabric interwoven with metal threads" , "Walking with a limp" , "Unable to walk properly" , "Crippled" , "Weak and unconvincing like injured foot" .)
