Place all ingredients in a blender. Blend until smooth.
Soak rice paper wrap sheets in a large bowl of hot water (not boiling) until soft.
Soak rice sticks in another large bowl of hot water (not boiling) until soft.
Place a towel on your work surface. Lay a softened rice paper wrap on the towel. In the center of the wrap, place a pinch of lettuce, cabbage, carrot and two avocado slices.
To wrap, fold two opposite sides of the wrap over the filling. Then bring the bottom of the wrap over the filling and roll away from you until the top is completely rolled onto the wrap. Try to wrap as tightly as possible without tearing it.
