Place the chickpeas, mustard, nutritional yeast and sea salt in a food processor and process until creamy and smooth.
Place in the fridge and chill for at least 30 minutes.
When you are ready to assemble, there are two ways you can do it.
You can either cut open the avocado, remove the pit and scoop the garbanzo mixture directly into the avocado halves and eat it just like that.
Alternatively, you can cut the avocado in half, take out the pit and then cut into slices. Next, scoop out the slices and cut them in half. Arrange the avocado pieces on a plate and top each one with the garbanzo mixture. Use this method if you want to serve as an hors d'oeuvre.
Whichever way you do it, be sure to sprinkle with paprika before serving.
