Preparation Mix rice, 1 Tbsp. coconut oil, a pinch of salt, and 5 cups water in a medium heavy saucepan. Cover and bring to a boil, then reduce heat and simmer until rice is al dente, about 25 minutes. Drain; set aside. Meanwhile, heat remaining 1 Tbsp. coconut oil in a large pot over medium. Add ginger and garlic and cook, stirring occasionally, until fragrant and just starting to brown, about 1 minute. Add broth, scraping the bottom of the pot with a wooden spoon to release garlic mixture, and bring to a simmer. Add squash and simmer 8 minutes. Add kale and cook, stirring, until vegetables are cooked through, 3–5 minutes. Whisk miso, tahini, sesame oil, and 1 tsp. salt in a medium bowl. Add 1/2 cup hot water and whisk until very smooth. When vegetables are cooked through, remove pot from heat and gently stir in tahini mixture (overheating tahini will cause it to separate). Season to taste, then immediately divide among bowls with brown rice. Top with scallions, sesame seeds, nori, and chili oil. Do Ahead Soup can be made 2 days ahead; chill in a resealable container. Reheat gently over low to avoid tahini from separating. Cooks' NoteHot chili oil is available at Asian markets and some specialty food grocery stores and online.
