Heat a ddukbaegi or pot over medium-low heat. Add oil and the white part of the scallions. Cook for 2 to 3 minutes, taking care not to burn the scallions.
Toss in the cubed pork shoulder and cook until the pork is no longer visibly pink.
Reduce the heat to the lowest setting then add gochugaru. Stir continuously for about 1 minute, making sure they don't burn.
Pour in the anchovy broth then bring to a boil over medium heat. Add onions, garlic, kimchi, and fish sauce. Simmer for 5 to 10 minutes or until the kimchi and vegetables soften to your liking.
Carefully add the tofu. Then, cover and simmer for 2 to 3 minutes.
Crack an egg into the jjigae and garnish with the green part of the scallions.
Serve with a fresh bowl of rice & enjoy!
