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 until golden brown and crisp.
03 - Halve the avocado, remove the pit, and scoop the flesh into a bowl. Add lemon juice, salt, and pepper, then mash with a fork until creamy and spreadable.
04 - Divide the mashed avocado evenly and spread generously over each toasted bread slice.
05 - Layer the tomato slices over the avocado, then arrange the sliced hard-boiled eggs on top. Drizzle with olive oil if desired.
06 - Finish with a sprinkle of fresh herbs and crushed red pepper flakes. Serve immediately while the toast is still warm and crisp.
