01 - Toast the bread slices in a toaster or on a dry skillet over medium heat until golden brown and crisp on both sides.
02 - Halve the avocado, remove the pit, and scoop the flesh into a mixing bowl. Mash with a fork to your desired consistency, then stir in the lemon juice, salt, pepper, and chili flakes if using.
03 - For fried eggs, heat a nonstick skillet over medium heat with a light coating of oil. Crack in the eggs and cook until the whites are fully set and the yolks remain runny, approximately 2 to 3 minutes. For poached eggs, bring a small pot of water to a gentle simmer, add a splash of vinegar, create a gentle swirl, and carefully lower each egg into the center. Cook for about 3 minutes, then remove with a slotted spoon and drain on a paper towel.
04 - Divide the mashed avocado evenly between the two toasted bread slices, spreading it in an even layer across each piece.
05 - Place one cooked egg on top of each avocado toast. Sprinkle with fresh herbs and finish with a light drizzle of extra virgin olive oil if desired. Serve immediately while warm.
