Cook the rice or 7-grain blend according to the package directions. Set aside to cool.
Optional for Crispy Grated Tofu:Preheat the oven to 425°F (220°C) or an air fryer to 400°F (200°C). Grate the super-firm tofu using the large holes of a box grater. Toss with the tamari, sambal oelek (or sriracha), nutritional yeast, and garlic powder until evenly coated. Toss with a drizzle of oil for more crispiness. Spread into a thin, even layer on a parchment-lined baking sheet or air fryer basket. Bake for 20–25 minutes, stirring halfway through, or air fry for 12–15 minutes, shaking the basket once or twice, until golden and crispy.
Blend the sauce: Add the tahini, miso, sambal oelek, garlic, maple syrup, lime juice, and water to a blender and blend until smooth. Thin with additional water as needed and season with optional tamari if desired.
Make the sushi bowls: Divide the grain blend among four bowls or meal-prep containers. Top with cabbage, cucumbers, carrots, and edamame.
Add toppings: Top with your choice of avocado, nori, pickled ginger, scallions, and sesame seeds. Divide the grated tofu between the four bowls, if using.
Add the sauce: Drizzle generously with the creamy tahini sushi sauce.
