1. Cut the tofu in half and place in a pot. Pour in enough water just to cover. Bring to a boil, and then lower to simmer for about 3-4 minutes. Drain and then place on a cutting board and cut into 1-inch thick triangles. Keep warm.
2. Meanwhile, place a frying pan over a medium heat, drizzle in the peanut oil. Add the garlic and sliced pork and stir fry for about 3-4 minutes until pork is cooked through.
3. Add the kimchi and fry for another 3-4 minutes, being careful not to brown. Add the spring onions and soy sauce and toss through just to wilt. Drizzle with the sesame oil. Place the kimchi pork stir fry in the middle of a plate and arrange the tofu on the side next to it.
4. Garnish with fresh chives and sesame seeds and serve with rice.
