Put all the ingredients outside of the avocado and the mayonaise in a bowl and mix it through the meat.

Take the meat and turn it into 8 flat patties.

Put a slice of avocado on half of the patties and put some mayonnaise inside the avocado hole.

Put the patties with nothing on it over the ones with the avocado, pinch the edges real good with your fingers to make sure that your patties are nicely sealed all around.
