Start by trimming and chopping the bok choy into bite-sized pieces. Mince the garlic and grate the ginger. Prepare all your ingredients beforehand for a smooth cooking experience.

In a large skillet or wok, heat the sesame oil over medium heat. Once the oil is hot, add the minced garlic and grated ginger. Sauté for about 30 seconds until fragrant but not burnt.

Toss in the chopped bok choy and stir-fry for 3-5 minutes. You want the leaves to become tender while still retaining a bit of crunch.

Stir in the chili sauce and soy sauce. Mix well to ensure all the bok choy is coated. Adjust seasoning with salt and pepper to taste.

Cook for an additional minute, then remove from heat. Serve hot, garnished with sesame seeds if desired.
