Simple avocado salad

Here is a simple salad based on one my cousin made a long time ago. It's just sliced avocado, red onion and bonito flakes (which I omitted here). I dressed it with a little soy sauce, lemon juice and plenty of black pepper and sesame seeds. I imagine a non-Asian version could be dressed with cilantro, lime and maybe tabasco? Or balsamic vinegar and olive oil. This salad is best with a more firm avocado, for those times when you must have an avocado but it's not fully ripe.
