Whisk egg with 1 teaspoon oil in a small dish then set aside.
Heat 1 teaspoon oil in a large wok or skillet over medium-high heat. Add seasoned protein of choice then stir fry until cooked through and remove to a plate.
Heat remaining teaspoon oil in the wok then add frozen mixed vegetables and green onions.
Stir fry until tender, about 2 minutes, then add garlic and cook for 30 more seconds.
Push vegetables to the side of the wok then add egg and sesame oil mixture into the center and scramble.
Add cooked protein, rice, and gluten-free Tamari or soy sauce to wok then toss well to combine.
Serve immediately.
