1. Cook quinoa: In a saucepan, bring water to a boil. Add quinoa, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let sit for 5 minutes, then fluff with a fork.
2. Heat olive oil in a wok over medium-high heat. Add onion and garlic, and sauté until fragrant.
3. Add bell pepper, broccoli, carrot, and snap peas. Stir-fry for 5-7 minutes until vegetables are tender-crisp.
4. Stir in cooked quinoa, soy sauce, sesame oil, and ginger. Cook for another 2-3 minutes, stirring frequently.
