I had granadilla (passion fruit) flavoured yoghurt this time instead of greek, and so thought I'd try it in a smoothie. Here goes!
3-4 pineapple rings, cored
2 heaped dessert spoons granadilla yoghurt (or more according to your taste)
1 cup orange juice
3 tbs ground flax seeds
Blend together. Yum-ums. Makes 2 large smoothies.
