Mix the rolled oats with ½ cup of cold water in a microwave dish. Add the salted butter and pepper to the mix, and microwave on high for 2 minutes.
Heat the olive oil in a saucepan over medium heat. Fry the egg until the white is firm and the yolk is still runny.
Once the porridge is ready, adjust its consistency by adding a little water as needed.
Arrange the egg on top of the porridge and garnish with avocado slices. Sprinkle with paprika or cayenne pepper. Add salt and pepper to taste, and drizzle on a little olive oil and soy sauce.
