In a clean coffee grinder or spice mill, buzz the green tea, crumbled nori, and sesame seeds together to a powder. Transfer to a small bowl and mix with the sea salt; set aside. With a sharp knife, slice the salmon into thin, 2-inch-long pieces. Lay a piece of fish in the palm of your hand and spread a very small amount of wasabi on the surface with your finger. Dab your fingers in a little water and grab about 2 tablespoons of sushi rice. While cupping your palm, gently press the rice onto the fish using 2 fingers. Hand-sculpt the sushi into the shape of a small football. Garnish with a paper-thin slice of cucumber draped over the top and a sprinkle of green tea salt. Squirt with a little lemon juice and serve. Awesome!
