Add your sunflower seeds to a large jar or bowl and cover with filtered water. Allow to soak for at least 3 hours, or overnight. Alternatively, you can quickly boil them to soften and strain.
Preheat your oven to 375F and prepare an oven save baking dish (mine measured roughly 11x7")
Heat a sauce pan with a touch of neutral oil and quickly sauté carrots, followed by onions and garlic for 2-3 minutes, until fragrant and lightly golden. Add vegetable broth and bring to a boil then lower to a simmer until the carrots are fork tender.
Transfer all of the mixture into a blender, add soaked and drained sunflower seeds, miso paste, nutritional yeast and salt and pepper. Blend until smooth and season to taste.
Add your rice to the baking dish, followed by the broccoli florets and then cover with your blended sauce. Use a spatula to gently stir to evenly distribute then cover with foil and pop in the oven for 20 minutes.
After 20 minutes, remove from the oven, gently stir again and bake for another 10-15 minutes uncovered. You may need to add additional time if the rice isn't cooked all the way through. At this point, you can also opt to add a sprinkle of vegan cheese shreds to top!
To finish, garnish with chives, cracked pepper and enjoy.
