In a medium saucepan, combine the rinsed quinoa and vegetable broth or water. Bring to a boil, then reduce heat to low and cover. Cook for 15 minutes or until all liquid is absorbed. Fluff quinoa with a fork and set aside.
In a large skillet or wok, heat olive oil over medium-high heat. Add the diced onion and sauté for 2-3 minutes until translucent.
Add the minced garlic and sauté for an additional 30 seconds until fragrant.
Stir in the diced carrots and bell peppers. Cook for about 5 minutes until they start to soften.
Add the snap peas and corn to the skillet, and sauté for another 3-4 minutes until all vegetables are tender-crisp.
Push the veggies to one side of the skillet and add the cooked quinoa to the other side.
Drizzle soy sauce and sesame oil over the quinoa and mix everything together, ensuring the sauce evenly coats the quinoa and vegetables. Cook for an additional 2 minutes to heat through.
Taste and season with salt and pepper as needed.
Remove from heat and garnish with chopped green onions and sesame seeds if desired.
Notes
Serve in bowls garnished with green onions and sesame seeds. Lime wedges add a nice touch.
