Press tofu to remove excess moisture and slice into long, thin matchsticks.
Slice the sushi-grade salmon into long, thin strips approximately 0.5-inch thick.
In a small bowl, whisk rice vinegar, honey, and sea salt until dissolved, then fold into the warm cooked rice.
Place a nori sheet on a bamboo rolling mat and spread half of the seasoned rice evenly, leaving one inch at the top.
Layer half of the salmon, tofu, and cucumber strips across the center of the rice.
Roll the mat tightly away from you, wetting the top edge of the nori with water to seal the roll.
Repeat with the second nori sheet and remaining ingredients, then slice each roll into eight pieces using a sharp, wet knife.
Serve immediately with tamari, wasabi, and pickled ginger for a bright, clean finish.
