01 - Toast the bread slices in a toaster or on a grill pan until golden and crispy to your liking.
02 - Halve the avocado, remove the pit, and scoop the flesh into a small bowl. Add lime juice, salt, and pepper, then mash with a fork until nearly smooth.
03 - Divide the mashed avocado evenly and spread a generous layer over each toasted bread slice.
04 - Spoon the chopped kimchi over each toast, distributing it evenly across both slices.
05 - Sprinkle with toasted sesame seeds and chopped green onions. Add red pepper flakes and a light drizzle of sesame oil if desired. Serve immediately while the toast is still warm and crisp.
