In a small bowl, add soy sauce, oyster sauce, Korean chili pepper flakes, minced garlic, and chicken bouillon powder. Mix until combined.
In a medium thick-bottomed pot, heat sesame oil and vegetable oil over medium heat. Add onion and green onion and sauté for 2 min or until fragrant.
Add your protein of choice and half of the chili peppers. Stir often so that the meat cooks evenly. Reduce the heat to low and add the seasoning paste. Stir-fry for about 3 minutes, but be careful not to burn it.
Now add the water and increase the heat to medium-high. Bring to a boil and add the diced shiitake mushrooms. Let cook for about 1 minute.
Add the silken tofu and break it into large chunks. Cook for another 1-2 minutes.
Bring to a boil and crack the eggs on top of the stew. Let it cook for 1-2 minutes.
Remove from the heat and garnish with green onions, chili peppers, and black pepper to taste. Serve with hot fluffy rice and kimchi. Dig in!
