Cut the kimchi and pork into bite-sized pieces.
Slice the onion, green onion, and tofu into suitable sizes.
Add sesame oil to a pot and stir-fry the pork first.
When the pork is cooked, add the kimchi and stir-fry together.
Once the kimchi becomes tender, pour in water and bring to a boil.
When the broth starts to boil, add the onion, green onion, and tofu.
Season with red pepper powder, minced garlic, and soy sauce.
Simmer over medium heat for 10-15 minutes, taste, and adjust the seasoning as needed.
