In a small pot, add sesame oil and ginger; then cook for 2-3 minutes
Add rolled oats and chicken broth. Bring to a boil, then lower the heat to a simmer. The oats will be cooked through and begin to thicken. Continue cooking until the oats are cooked or until you reach the consistency you want, about 15 minutes
Add fish sauce, soy sauce, and white pepper. Stir, and garnish with scallions
