Rinse the rice under cold water until the water runs clear. Add to a medium saucepan over high heat and toast for 3–4 minutes, stirring occasionally.
Pour in half the can of coconut milk (about 200 ml) and ½ cup of water. Add a generous pinch of salt. Stir, then cover with a lid and bring to a boil. Reduce heat to low and simmer for 15 minutes. Turn off the heat and let steam, covered, for another 10 minutes.
While the rice cooks, dice the red onion, chop the broccolini (including stems), coarsely chop the peanuts, and drain and rinse the chickpeas.
Heat the vegetable oil in a large skillet or sauté pan over medium heat. Add the onion and chickpeas and cook for 3–4 minutes, stirring occasionally.
Add the smoked paprika, turmeric, garlic powder, cayenne (if using), broccolini, and chopped peanuts. Cook for 2 more minutes, stirring to coat the veggies and chickpeas in the spices.
Pour in the remaining coconut milk and add the miso paste. Stir well until the miso is fully dissolved. Add the remaining ½ cup water and simmer for 8–10 minutes, or until the sauce has slightly thickened. Stir in 1½ tablespoons of the shredded coconut and season with salt to taste.
Fluff the rice with a fork and divide between bowls. Spoon the curry on top and garnish with fresh cilantro and extra shredded coconut, if using.
