Creating this savory oatmeal with a soft-boiled egg is a simple and straightforward process. Follow these steps to enjoy a delicious breakfast in just 15 minutes:

1. Boil the Liquid: In a pot, bring the water or vegetable broth to a boil. Using broth instead of water can add extra flavor to your oatmeal.
2. Cook the Oats: Stir in the rolled oats and reduce the heat. Allow them to cook for about 5 minutes until they reach a tender consistency.
3. Prepare the Egg: While the oats are cooking, fill a small pot with water and bring it to a boil. Gently add the egg and cook it for 6-7 minutes to achieve a soft-boiled texture.
4. Cool the Egg: Once the egg is done, drain the hot water and run the egg under cold water to stop the cooking process. Carefully peel the shell.
5. Add Spinach and Soy Sauce: Stir the spinach and soy sauce into the oats, allowing the spinach to wilt.
6. Assemble the Dish: Serve the oatmeal in a bowl and top it with the sliced avocado and the soft-boiled egg. Season with salt, pepper, and any optional toppings like red pepper flakes or green onions.
