Prepare the ingredients: Begin by dicing the chicken breast into bite-sized pieces. Rinse the rice under cold water until the water runs clear to remove excess starch.

Cook the rice: In a pot, combine the rinsed rice with water according to package instructions. Bring to a boil, then reduce the heat, cover, and let it simmer until the rice is tender and the water is absorbed (approximately 15-20 minutes).

Cook the chicken: While the rice is cooking, heat a tablespoon of oil in a skillet over medium-high heat. Add the diced chicken breast and sauté until golden brown and cooked through, about 7-10 minutes. Make sure to stir occasionally for even cooking.

Heat the sauce: In a separate pot, gently heat the sweet and sour sauce with vegetables over medium heat until warmed through, stirring occasionally to combine the flavors.

Combine the dish: Once the chicken and rice are cooked, add the cooked chicken to the pot with the heated sauce. Stir well to coat the chicken evenly with the sauce.

Serve: Fluff the cooked rice with a fork and spoon it onto plates. Top with the sweet and sour chicken mixture and enjoy your meal!
