Put 1 cup dry rice in a medium size pot with two cups water. Cover and bring to a boil. Reduce heat to low and cook 20 to 25 minutes. Remove from heat once water has evaporated and rice is tender and fluffy, leaving lid on.
While rice is cooking, in a separate bowl mix together sliced cucumbers, carrots, lime juice, ume, and sesame oil. Toss lightly and set aside.
If you have a mortar and pestle and you want to throw in an extra flourish, use it to slightly crush the shichimi togarashi, releasing the flavors and oils. It’ll be fine to use it un-crushed, too. In a small bowl, whisk together the olive oil, apple cider vinegar, shichimi togarashi, sea salt, and agave until the liquids are fully incorporated.
In a medium sized bowl, mix 2 cups of cooked rice with your shichimi togarashi dressing and sushi nori. Distribute amongst bowls and top with cucumber carrot salad, chopped greens, avocado, tahini, and a drizzle of soy sauce. An extra sprinkle of seeds never hurts.
