Lightly grease the waffle maker (I give it a light spray with olive oil) and turn it on to heat up.
In a bowl add the mozzarella, egg and almond flour. Mix well.
Spoon the batter into your waffle maker. If you are using a small waffle maker spoon half the mixture in at a time. Gently spread it out towards the edges.
Close the lid and cook for 5 minutes.
Whilst the chaffle is cooking make the avocado topping. You can serve the avocado either sliced or mashed.
If you are serving mashed: Remove the pit from the avocado, scoop out the flesh and place in a bowl. Mash with a fork and mix it the lemon juice, salt and pepper.
If you are serving sliced: Cut the avocado in half and remove the pit from the avocado. Carefully scoop out the avocado halves with a large spoon and place on a cutting board. Slice the avocado and sprinkle with the lemon juice, salt and pepper.
Using tongs, remove the cooked chaffle and place on serving plate.
Spread the avocado mash on top of the chaffle or place the avocado slices in a fan shape and eat immediately.
