In a small bowl, whisk together the minced ginger, soy sauce, rice vinegar, minced garlic, sugar, 1 tablespoon of the sesame oil, cornstarch, and chili paste. Set aside to allow the flavors to meld.
Heat the vegetable oil in a wok or large skillet over medium-high heat. Add the sliced chicken and stir-fry for about 5-7 minutes or until the chicken is cooked through and lightly browned. Remove the chicken from the wok and set aside.
In the same wok, add the remaining tablespoon of toasted sesame oil. Once hot, add the red onion and stir-fry for 2 minutes until it starts to soften. Then add the bok choy and stir-fry for an additional 3-4 minutes until the leaves are wilted and bright green.
Return the cooked chicken to the wok with the vegetables. Pour the prepared sauce over the chicken and vegetables, stirring well to combine. Cook for another 2-3 minutes, allowing the sauce to thicken and coat everything beautifully.
Remove the stir-fry from heat. Garnish with crushed dry-roasted peanuts and torn basil. Serve over coconut jasmine rice or cauliflower rice for a low-carb option.
