Cut the ahi tuna into bite sized pieces and add it to a bowl. Add the soy sauce, ginger, sesame seeds, and sesame oil. Toss to coat and let it marinate while you make the rest of the bowl.
Thinly slice the cucumber and avocado. Divide the greens and rice into the base of two bowls. Top with cucumbers, avocado, ahi tuna, and sushi ginger. Enjoy!
