Roughly chop the pineapple and apricot halves into large pieces. Put them into the blender with the orange juice and mix for 20 seconds on speed 2. Pour the smoothie into a large glass.
Put the pistachios, almonds and dried apricots into the mini-grinder and give 10 pulses on speed 2 to produce very small cubes. Arrange the dried fruit and nuts on the smoothie, decorate with a slice of orange and serve.
Tips: This smoothie can be made with 2 fresh, very ripe apricots instead of canned apricots. Taste and add 1 or 2 tablespoons runny honey to sweeten.
