If chocolate is not already in rounds (as in couverture rounds, or chips) break it up a little. Place in bowl. I melt chocolate using the microwave method. Zap for about 1 minute, stir, zap again for 30 seconds, stir, give it a minute to finish melting. If it needs an additional 30 seconds, zap again. The amount of microwaving needed will vary with your machine.
Blend avocado and banana in your blender or food processor.
Add melted chocolate and vanilla and blend again.
Add a tiny bit of salt (optional).
Add optional flavoring(s) if desired.
Serve immediately.
