How to make
Cut the avocado, carve out the edible part, put it in a bowl and immediately pour the lemon juice over it. Season the avocado with salt and mash it with a fork.
Spread half of the slices with the resulting mixture. Add two slices of bacon and sliced mozzarella and blue cheese on top.
Cover the sandwiches with the other half of the slices and place them in a toaster to be toasted.
In the toasted sandwiches, place a slice of tomato and an Iceberg lettuce leaf.
