This is really easy to make and is made of natural ingredients so not only does it taste good, but it's just fruit and yoghurt...
Ingredients:
1 Mango, nearly over ripe (very squishy)
2 small Limes
1 tub Greek Style Yoghurt
Method
Wizz together the lime and the mango in a small bowl (I used a huge mug) until smooth. Add the yoghurt to taste (don't add all at once, add a small amount and taste, if it needs more add more) and mix thoroughly. Pour into small tubs and put in the freezer until frozen...et voila!
