Preheat oven to 400°F and line a rimmed baking sheet with parchment paper.
Combine the quinoa, broth, and salt in a sauce pan, and bring to a boil over high heat.
Once the water boils, reduce heat to medium-low, cover, and simmer until quinoa absorbs all of the water and is tender about 15 to 20 minutes. Then, turn off heat and let stand, covered, for 5 minutes. Fluff with a fork to separate the grains
Add the veggies and sausage to the baking sheet.
Place the pan in the oven and bake for 15 minutes. Gently remove the pan from the oven, flipping the veggies after 15 minutes, and then baking for an additional 10-15 minutes, or until the veggies are tender and the meat is heated through. Serve with quinoa.
