01 - Bring a small pot of water to a rolling boil. Gently lower the eggs into the water and cook for 9 to 10 minutes until hard-boiled. Transfer to cold running water to cool, then peel and slice into rounds.
02 - While the eggs cook, toast the bread slices in a toaster or on a skillet until golden brown and crisp.
03 - Halve the avocado and remove the pit. Scoop the flesh into a bowl and mash together with fresh lemon juice, salt, and freshly ground black pepper until smooth and creamy.
04 - Divide the mashed avocado evenly between the two toasted bread slices, spreading it edge to edge in an even layer.
05 - Arrange the thinly sliced tomato over the avocado spread. Top with the sliced hard-boiled eggs, distributing them evenly across each slice.
06 - Drizzle with olive oil if desired. Garnish with freshly chopped herbs and a pinch of crushed red pepper flakes. Serve immediately while the toast is still warm and crisp.
