I think what you are doing already is good enough..thats exactly what i feed mine minus the flakes..
Hikari Wafer's seem to be the best wafer's ive tried they love them...and courgette is also their favourite meal..
I think there is a post somewere on here that jakob posted and it shows you a nice list of diff veggies you could try..
But you cannot go wrong with Hikari Wafer's..
