Cook the ramen noodles according to package instructions. Drain and set aside.
In a large pot, heat the vegetable oil over medium heat. Add the ground pork and cook until browned, breaking it up with a spoon, about 5-7 minutes.
Stir in the minced garlic and ginger, cooking for an additional 1-2 minutes until fragrant.
Add the soy sauce, tahini, and chili paste to the pot, mixing well to combine.
Pour in the chicken broth and bring the mixture to a simmer. Let it cook for about 5 minutes to allow the flavors to meld.
Stir in the sesame oil, chopped green onions, and baby spinach. Cook for another 2-3 minutes until the spinach is wilted.
Divide the cooked ramen noodles into bowls and ladle the spicy broth and pork mixture over the top.
If desired, top each bowl with a soft-boiled egg and sprinkle with sesame seeds before serving.
