I'm looking for some nice simple but tasty smoothie recipe ideas.

No Pineapple or avocado based ones though. I can't stand either of them. Unless they are very minor to to recipe.

I have already made a raspberry and banana smoothie which was quite nice but a bit bland.

What I put in mine:

banana
frozen mixed berries (raspberry, strawberry, blueberry, blackberry, red currant)
kiwi
Greek yogurt
whole milk
water
olive oil
almonds
squeeze of lemon juice

I don't have all of these things every time of course, but I always try to have the almonds, yogurt, and olive oil with some of those fruits in the smoothie. The taste of olive oil isn't detectable in the smoothie.

Mmmm never thought about nuts in a smoothie before I'll have to order some in my next shop

I sometimes add a little cordial to pep them up. It works almost like a seasoning, bringing the flavours to life without adding extra sugar. Vanilla extract is another one, goes well with peaches or bananas. Otherwise, I love a mango lassi: just tinned mango pulp and yoghurt. Most brands of the pulp have added sugar, sadly.

Mango or peaches is my favourite. Bung in some oats and frozen yoghurt and blitz.

I had a lovely drink in Sydney made from green apples.
