In a medium saucepan, combine quinoa and vegetable broth. Bring to a boil, reduce heat to low, cover, and simmer for about 15 minutes, or until liquid is absorbed. Fluff quinoa with a fork and set aside.
While the quinoa cooks, chop carrots and green onions, and mince garlic. If using frozen peas, ensure they are thawed.
In a large sauté pan or wok, heat olive oil over medium-high heat. Add carrots and cook for 3-4 minutes until softened. Add garlic and green onions, stirring for another minute until fragrant.
Stir in thawed peas, cooking for another 2 minutes until heated through.
If using eggs, push vegetable mixture to one side and pour beaten eggs into the other side. Scramble until fully cooked, then mix into the vegetable mixture.
Add cooked quinoa to the pan, along with sesame oil and soy sauce. Stir until well combined and heated through. Adjust seasoning with salt or more soy sauce as desired.
Remove from heat and serve immediately, garnished with additional green onions if desired.
