01 - Bring a small pot of water to a rolling boil. Gently lower the eggs into the water and boil for 9 to 10 minutes until hard-boiled. Transfer to cold running water, 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, remove the pit, and scoop the flesh into a mixing bowl. Add lemon juice, salt, and pepper, then mash with a fork until smooth and creamy.
04 - Divide the mashed avocado evenly and spread a generous layer over each slice of toasted bread.
05 - Arrange the thinly sliced tomato over the avocado spread on each toast.
06 - Place the sliced hard-boiled eggs over the tomato layer. Drizzle with olive oil if desired.
07 - Sprinkle with freshly chopped herbs and crushed red pepper flakes to taste. Serve immediately while the toast is still warm and crisp.
