To prepare the vegetables, start with cutting the zucchini into thin slices. Next, cut the carrots and sweet peppers into thin slices as well. Set them aside along with sliced onions. Use canned mushrooms if available.
For the chicken, slice boneless chicken breasts into thin slices. Season the chicken with salt, black pepper, garlic, ground ginger, soy sauce, white vinegar, sodium carbonate, and an egg. Add corn starch gradually until the desired texture is achieved.
Prepare the sauce by combining water, ketchup, white vinegar, sugar, soy sauce, salt, and pepper. Heat the oil and fry the chicken in batches. Once done, fry the vegetables in butter separately. In a large pan or wok, stir fry the vegetables and add the sauce. Thicken the sauce with corn starch mixture and toss in the chicken. Stir well and serve.
