This Guacamole is quite amazing; easy, yummy and with no additional fat other than the avocado. No need to spend a lot of time chopping the ingredients as the blender will do the job anyway. The key is to add salt and lime juice 'to taste'; a bit more salt makes all the difference to bring out the avocado's flavour. Regular onion will work instead of red onion. It's best to use rubber gloves when working with hot peppers.
