Heat oil in a large wok over medium high heat. Add whisked eggs to wok, let cook and set for a minute. Break up eggs with your spatula or spoon (I use this bamboo stir fry spatula) into small pieces. Add frozen mixed vegetables and cook for 2 minutes, stirring frequently. Add brown rice and soy sauce to vegetable and egg mixture and cook for up to 5 minutes or until all is heated through. Season well with coarse salt, fresh ground pepper and additional soy sauce to taste. Serve with red chili sauce or sriracha.
