Place the black rice, 3 cups of water, and a pinch of salt in a medium saucepan. Bring to a boil, reduce to simmer, cover and cook 25-30 minutes.
In a bowl, whisk together the soy sauce, ginger, and sesame oil. Add the cubed tofu, toss to coat, and set aside to marinate.
In a small saucepan, combine the tahini, coconut milk, curry paste, lime juice, soy sauce, and brown sugar. Cook over medium-low heat, stirring constantly, until the mixture thickens slightly. If you prefer a thinner sauce, add more coconut milk.
Heat 1 tablespoon oil in a saute pan over medium-high heat. Add the tofu in a single layer and cook until slightly crispy on all sides. Remove to a paper towel-lined plate.
Place a handful of spinach in each bowl, add a scoop of black rice, tofu, and drizzle with tahini sauce.
Top with carrots, cucumbers, sprouts, and peanuts.
