Clean the mushrooms and discard or any large stems. Preheat the grill to high. Brush the mushrooms all over with 1 tablespoon of olive oil and season with a little salt. Arrange top side down under the grill for 7-10 minutes until cooked through and tender.
Step 2
Whilst the mushrooms are cooking, heat a tablespoon of olive oil in a frying pan over a medium heat. Add the eggs and fry until the yolk is cooked to taste.
Step 3
Whilst the eggs are frying, peel and diced the avocado and add to a mixing bowl with the lime juice, ½ tablespoon of olive oil, the chilli flakes and a pinch of salt. Mash together roughly to combine and form a chunky paste.
Step 4
To assemble the mushroom stacks, divide the guacamole evenly between the two mushrooms.
Step 5
Top each with a fried egg and for added spice, sprinkle extra chilli flakes over to serve.
