Drain and rinse the chickpeas under running cold water.
In a bowl, mash them with a fork. I like to have a bit of texture, so I generally crush them slightly.
Add avocado, salt, pepper, and mustard and do the same with the fork - crush/mash it together.
Mix in the onions.
Divide the mixture, and wrap it into two wraps with a handful of lettuce.
Toast the wraps in a panini grill or on a dry pan and enjoy.
