Oh I didn't see this hun!
I buy the frozen fruit, it's well nice ... then add spinach, milk/water ... even natural greek yogurt.Of course I add whey protein to my smoothies too.
Raspberries - vanilla whey - spinach - almond milk
Strawberries & bananas - vanilla whey - spinach - almond milk
Raspberries - water - vanilla whey - natural yogurt - spinach
Cherries - chocolate whey - coconut milk
With or without the spinach on the above ... Not ventured any further yet as it all costs I guess. I also made some up couple of days ago and poured them into ice lolly moulds
You could also add chia or flaxseeds in smoothies!
