Add quinoa and veggie broth to a medium sized pot and bring to a boil.
Lower the heat and let simmer for 15-20 minutes or until all the liquid has absorbed.
Meanwhile, in a medium-sized skillet, toss together the tomatoes, zucchini, diced onion, oregano, and olive oil.
Sprinkle with salt and sauté over medium-high heat until all the vegetables are tender (about 5-7 minutes)
Add the quinoa to the pan and toss gently to combine. Serve hot.
