Mash it all together!!!
In the meantime, bring a pot of water to a boil

Crack each egg to a small bowl and gently pour it onto the boiling water
Once all the eggs are in, use a wooden spoon and stir gently to make sure that the eggs do not stick to the bottom of the pot
Cook eggs for 3 minutes, then take out and let dry

Assemble the toast: smash avocado on the toast, sprinkle with red pepper flakes, top with the egg and server immediately with cherry tomatoes cut in a half; be sure to sprinkle with salt and olive oil.
