Bluefin tuna tartar over guacamole

Cut the bluefin tuna into not too small or too large cubes.

Marinate with soy, sesame sauce (little, which gives a lot of flavor), lime.

Add finely chopped red onion, chives and cilantro.

Make a guacamole to put on the base (see guacamole recipe).

Serve in a martini glass, placing the guacamole as a base and the tuna tartar on top.
