Here's what I did:
Handful spinach blitzed with almond milk first, as usual!
Then added a banana and 3 clementines, peeled and as much pith removed as I could be bothered to do.
I also added 2 heaped dessert spoons full of Greek yogurt. I don't normally put yog in my smoothies anymore but I needed some protein and didn't want to mess up the citrus taste with hemp protein and I thought it might be a bit acidic or astringent or just too runny without it.
Anyway, the upshot is it worked really well. A very delicate light orangey taste but nice and creamy and fresh tasting. Just sweet enough thanks to the yog and banana.
It's nice to mix things up with the green smoothies and experiment with different combos here and there and this was a nice quick, simple one that did the trick nicely this morning.
