Slice the chicken breast thinly across the breast, to get bite-sized strips.
3 Chicken breasts
Add the sliced chicken breasts into a large mixing bowl. Combine with baking soda, corn starch, and soy sauce. Let the chicken sit in the marinade for 15 minutes.
1 tbsp Soy sauce, 2 tsp Corn starch, 2 tsp Vegetable oil, ¾ tsp Baking soda, 3 Chicken breasts
While the chicken is resting, mix together the ingredients for the black pepper sauce in a small mixing bowl. Mix together until there are no visible clumps of corn starch left.
3 tbsp Soy sauce, 2 tsp Dark soy sauce, 2 tsp Rice wine vinegar, 1 tbsp Sugar, 1 ½ tsp Black pepper, 1 tbsp Corn starch, ¼ cup Chicken broth
Heat a large skillet or wok over high heat. Add oil and the marinated chicken to the pan. Let the chicken sit untouched in the pan for 2-3 minutes to sear. Once the chicken is almost opaque from the bottom, toss the chicken to lightly cook the other side. Remove the chicken from the pan and set aside in a bowl.
To the same pan, add one tablespoon of oil and the chopped vegetables. Mix in the minced ginger and garlic, and sauté until the peppers and onions have slightly softened.
1 Onion, 1 Green pepper, 1 Red pepper, 1 tbsp Ginger paste, 1 tbsp Garlic paste
Add the cooked chicken back to the pan with the vegetables, and pour the prepared sauce into the pan. Combine well, and let the sauce thicken until it coats the chicken and vegetables.
