Smoothie recipes please

Hi all

Im starting doing smoothies in the morning for breakfast.

So far I have only done fruit which of course chucks my sugar (natural) up high.

Does anyone have tried and tested (that dont taste like dirt) veggie smoothie recipes that I can do?

Im very apprehensive about doing veggie ones so I thought if people had tried them and they tasted ok it might give me more incentive.

Thanks so much.
