At least 2 hours ahead, peel and slice one banana and freeze the slices in a container.
Let the acai packs stand at room temperature for 2-3 minutes, then break them into pieces and put them in a blender with the frozen banana slices and the apple juice.
Blend on low speed, pushing the mixture down with a spatula, until thick and smooth like soft-serve ice cream. Add a splash more juice only if the blender stalls.
Peel and slice the second banana, and hull and slice the strawberries.
Spoon the acai mixture into two chilled bowls.
Top with the granola, banana slices, strawberries and blueberries and serve immediately.
