Bring water or broth to a boil in a medium saucepan over high heat. Add brown and wild rice blend and return to a simmer. Reduce heat to medium low, to maintain a simmer and cover. Simmer until the rice is tender and the water is absorbed, according to the package instructions.

Toss chicken thighs, paprika, the remaining 1 teaspoon oil, the remaining ½ teaspoon of herbs and the remaining ½ teaspoon of salt in the bowl until coated. Arrange among the Brussels sprouts.
Roast the Brussels sprouts and chicken, rotating the pan, and stirring the sprouts once, until the chicken is cooked through and the sprouts are tender, and browning, 26 to 30 minutes.
Meanwhile, stir together maple syrup, balsamic vinegar and Dijon mustard.
Drizzle the maple mixture over the hot Brussels sprouts and chicken, sprinkle with pepper and serve with the rice.
