Clean the radish. Peel the skin if necessary. You don't need to peel if the skin is smooth and clean.Cut the radish into match sticks (use a mandoline if available).
Heat a large skillet with a tablespoon of oil over medium heat. Add the radish sticks with the optional soup soy sauce, salt, and garlic and cook for 4 - 5 minutes, stirring well, until the radish sticks become wilted and translucent.
Add 1/4 cup of water. Reduce the heat to medium low, cover, and cook for an additional 3 - 4 minutes, until it reaches the desired level of softness. Taste and adjust seasoning and/or cooking time as needed. Right before turning off the heat, add the chopped scallion, sesame oil, and sesame seeds, and stir well. Serve warm.
