Cut the chicken breast into small pieces. Marinate with soy sauce, salt, sugar, black pepper, and sesame oil. Coat the chicken pieces in cornstarch, then fry in hot vegetable oil. Slice the bell pepper and green onions into thin strips. Cut the pineapple into cubes. Peel and slice the carrot into rounds, then cook in hot water with sugar until just tender.

Sauté diced onion with garlic, seasoning with black pepper, cumin, and paprika. Sauté until fragrant, then add the pineapple, carrot, and tomato sauce. Add the fried chicken pieces and pineapple juice, stir, and season with salt to taste. When the sauce thickens from the fried chicken, turn off the heat and add the green onions.

Serve with white rice or Chinese noodles.
