Gather your Ingredients. I also want to say thank you to Mark Matsuoka for his "how to sear tuna guide" which I added into my guide.
Add all ingredients to a bowl to marinade the tuna. Once the ingredients are mixed, add the tuna steaks to marinate. Marinate the tuna for 30 mins.
I like onions, so I grilled them on med-high get for 10 mins or until browned.
Here is my version of Japanese inspired seared ahi. I added avocados on the top and served with grilled onions an spinach.
