'mundane' is the definition.
(synonyms)

'way to welcome home?' is the wordplay.
'way' becomes 'e' (Compass direction - East).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'welcome' becomes 'rout' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'home?' becomes 'in' ('he's home' can mean 'he's in').
'rout'+'in'='routin'
'e' after 'routin' is 'ROUTINE'.
