Start by pre-heating the oven to 375°F.
To make the mushroom bacon, add the sliced mushrooms to a large mixing bowl with the rest of the ingredients. Mix well, so that the oil and coconut aminos absorb into the mushrooms. On a parchment paper lined tray, spread the mushrooms out evenly, make sure none are overlapping - this will make the bacon soggy. Bake for 20-25 minutes. When the mushrooms are cooked and crisp, remove from the oven and set aside to cool - this is when the mushrooms harden and get even crispier.
In the meantime, prepare the avocado dressing. Simply add all the ingredients into a food processor or blender and mix until creamy.
To assemble the sandwich, first add a generous layer of avocado cream to the toast, then the cucumber, lettuce, sprouts, radishes and crispy bacon. Enjoy!
