In a medium-sized saucepan add oat bran, water, milk, garlic powder, onion powder, kosher salt, and black pepper.
Bring to a boil over high heat, reduce heat and cook for 1-2 minutes, stirring occasionally.
When fully cooked divide into 2 bowls.
While the oat bran cooks, in a small skillet add sesame oil and set over medium-high heat.
When the oil is hot add the shiitake mushrooms and saute for a few minutes or until the mushrooms are starting to soften.
Add the green onion and soy sauce and saute for a few more minutes or until the onions are softened and the soy sauce is cooked into the mushrooms.
To serve, divide the mushrooms equally between the bowls and spoon over oat bran.
Top each bowl with a fried egg and garnish with crushed red pepper flakes, black sesame seeds, sriracha, sliced green onion, and sesame oil.
