Have all the ingredients cut and ready. This is a very simple recipe, but packed with flavour.
On a plate lay the cucumber and set aside
Mashed the avocado and add some lime juice and salt and lay it on top of the cucumber.
Then just place the fresh tuna on top of the avocado (do it in a nice way, so it look pretty)
Then add a bit of red onion, chilli slices and some coriander leaves.
Finish it off with lime juice, salt and sesame seeds.
Eat it on top of tostadas or biscuits and add some chilli oil to add even more flavour.
