Preheat the oven to 425F. Line a baking sheet with parchment paper. Add chicken and broccoli to the baking sheet. Drizzle with the oil and salt and toss to coat. Spread out into an even layer and bake for 15 minutes, or until chicken is cooked through.
In a medium-large pot, add the rice and enough water to cover by 2 -inches. Bring to a boil, then reduce the heat to medium to maintain a rapid simmer for about 30 minutes, or until cooked through. Drain and set aside.
In a medium bowl, mix together the sunflower cream, maple, vinegar, soy sauce, and garlic.
Serve chicken, broccoli, and rice topped with lots of sauce, herbs, toasted nuts or seeds, and sriracha (if using).
