In a medium bowl, combine the soy sauce, dark soy and cornstarch. Whisk to blend well, and add the chicken to the sauce. Toss to evenly coat the chicken and set aside for 15 to 20 minutes.
In a medium bowl, combine the ketchup, stock, chili garlic sauce and sugar. Stir to combine and set aside until ready to use. Place a wok over high heat and add the vegetable oil to the pan. Swirl the wok to be sure to coat well with the oil. Add the ginger, garlic, green onions, dried chilies and jalapenos to the wok.
Cook, stirring often until the garlic is fragrant and the chilies begin to brown, about 20 to 30 seconds. Add the chicken, bell peppers and onions to the pan and stir-fry until the chicken is no longer pink, about 4 to 5 minutes.
Add the sauce to the pan and bring to a boil, being sure to toss well in order to coat all the chicken and vegetables evenly, about 1 to 2 minutes. Sprinkle the sesame seeds, sesame oil and cilantro into the pan and toss to combine. Remove from the heat and serve on a platter with steamed white rice.
