Gather the ingredients so you have everything close at hand on the counter or table.
Prepare the Ingredients
Using a Chef’s knife and cutting board, slice 1 1/2 pounds chicken tenders into 1-2 inch pieces.
With a second cutting board and with a clean knife, peel and slice 2 medium carrots, 1 large green bell pepper, and 1/2 medium sweet onion. Mince 1 tablespoon minced garlic. Set aside until ready to use.
Drain 20 oz. pineapple chunks, reserving juice for the sauce. (Add enough water to the drained pineapple juice to make 2 cups. You will add the chicken bouillon cube to this later in this recipe.)
Prepare 1 1/2 cups long-grain white rice, following package directions, which should take approximately 18-20 minutes to cook.
Cook the Chicken and Vegetables
Mix together 1 cup all-purpose flour, 1 tablespoon seasoned salt, and 1/2 teaspoon freshly ground black pepper in a large plastic bag. Add in chicken pieces and toss to coat.
In a large cast iron skillet, heat 5-6 tablespoons vegetable oil over medium high heat. When the skillet is hot and the oil is shimmering, place breaded chicken pieces in the skillet and brown on all sides, about 6-8 minutes. Transfer chicken to a large bowl. Cover to keep warm.
If necessary, drizzle more vegetable oil to the skillet and add prepared carrots, green bell pepper, sweet onion, minced garlic, and pineapple chunks. Cook for another 8-10 minutes until vegetables are tender. Transfer the vegetables to the bowl with the cooked chicken pieces.
Prepare the Sweet and Sour Sauce
In a medium bowl, combine 2 tablespoons red wine vinegar, 2 tablespoons soy sauce, 1/3 cup brown sugar, 1/4 cup ketchup, 2 tablespoons cornstarch, and 1 teaspoon ground ginger. Whisk together until smooth.
Pour the reserved 2 cups pineapple juice + water into the skillet along with 1 cube chicken bouillon. Bring to a boil and stir until the bouillon cube has dissolved. Add in the sauce mixture and cook for 2-3 minutes, stirring frequently until thickened.
Add chicken and vegetables to the sweet and sour sauce. Stir together until the chicken pieces are completely coated with the sauce.
