Add the beaten eggs to the oil, scrambling them and breaking them up into smaller pieces with your wok spatula just until done. Transfer them to a large bowl and set aside.
Add 1 tablespoon oil around your wok. Add the sausage, and stir-fry for 20 seconds. Add the onion, scallions, carrots and garlic to wok and stir fry 1-2 minutes until onion is translucent. Remove and add to large bowl. Set aside.
