Peel of your avocados skin and mash your avocados with a fork or hand grinder. (We use a fork because it gives a better texture)
Now add onions, tomatoes, salt, lemon juice, and cumin powder inside your mashed avocados and mix everything together with a light hand.
Your guac is ready!
Preheat your oven at 180 Degrees Celcius.
Slice your Panini Bread in half (not completely!) so it becomes like an open book.
Put one slice of cheese on your bread and put it in your oven for 2-3 minutes until the cheese melts.
Take the bread out of the oven and open it like an open book and spread some guacamole on top.
Now add some tomatoes, jalapenos (optional), cucumbers, and lettuce on top of the guac as well!
Now add a layer of your nachos on top as well (make sure they are not powdered but not too big!)
Close up your sandwich and enjoy eating!
