Cook quinoa in advance and preferably chill overnight. If that’s not possible, try to chill the cooked quinoa for at least 2 hours before starting the rest of this recipe.
In a large pan, heat 2 Tbsp oil and 1 Tbsp butter over medium heat. Add onions and sauté until soft and translucent, about 3-4 minutes. Add frozen veggies and zucchini and saute until cooked through. Remove to a bowl and set aside.
In the same pan, heat 2 Tbsp oil and 1 Tbsp butter until butter is melted. Add the chilled quinoa and saute, stirring frequently, until quinoa begins to brown. Add 1 Tbsp soy sauce and salt and pepper to taste. Remove the quinoa to a bowl and set aside.
Add 1 Tbsp oil to the pan and crack the eggs into the pan. Stir the eggs while cooking until eggs are cooked through. Season with salt and pepper.
Add the quinoa and vegetables to the eggs and stir until combined. Add remaining tablespoon of butter and season with salt and pepper. Turn off the heat and serve.
Top with sliced green onions, hot sauce, and more soy sauce, if desired.
