In a large pot, heat vegetable oil over medium heat. Add the minced garlic and grated ginger, and sauté until fragrant (about 1 minute).
Add the chopped bok choy, julienned carrot, and sliced red bell pepper to the pot. Sauté the vegetables for about 3-4 minutes, until they start to soften.
Pour in the chicken or vegetable broth and bring to a gentle boil.
Stir in the chili garlic sauce, soy sauce, and sesame oil. Let it simmer for another 2 minutes for the flavors to meld.
Add the ramen noodles directly into the pot and cook according to the package instructions, usually about 3-4 minutes, until the noodles are tender.
Once cooked, remove from heat and stir in the chopped green onions.
Serve the ramen in bowls, topped with a boiled egg if desired, and sprinkle sesame seeds over the top for garnish.
Notes
Add a boiled egg for extra protein and garnish with sesame seeds.
