In a medium saucepan, combine the rinsed quinoa and 2 cups of vegetable broth or water. Bring to a boil over medium-high heat, then reduce to low, cover, and simmer for about 15 minutes until liquid is absorbed. Fluff with a fork and set aside.
In a large skillet or wok, heat the 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 aromatic.
Add the diced carrots and bell peppers, cooking for about 5 minutes until they begin to soften.
Toss in the snap peas and corn, continuing to sauté for another 3-4 minutes until tender-crisp.
Push the sautéed vegetables to one side of the skillet and add the cooked quinoa to the other side.
Drizzle the soy sauce and sesame oil over the quinoa, stirring to coat evenly. Cook for an additional 2 minutes to heat through.
Remove from heat and taste, seasoning with salt and black pepper as needed.
Transfer to serving plates and garnish with chopped green onions and sesame seeds if desired.
Notes
Serve in vibrant bowls with lime wedges for a zesty boost.
