In a large pot, combine chicken broth, soy sauce, sesame oil, and chili paste. Bring to a simmer over medium heat.

Once simmering, reduce heat to low and let it cook for 10 minutes to allow flavors to meld.

In a separate pot, bring water to a boil. Add ramen noodles and cook according to package instructions, usually about 4-5 minutes.

Drain and rinse under cold water to stop cooking. Set aside.

In a skillet, cook ground pork over medium heat until browned. Season with salt and pepper.

Blanch bok choy in boiling water for 1-2 minutes until tender, then drain.

In serving bowls, place a portion of noodles. Ladle the hot broth over the noodles.

Top with ground pork, bok choy, chopped green onions, a dollop of peanut butter, and sprinkle with sesame seeds.
