Stir-fried Sweet and Sour Pork

Instructions:

1. Cut the pork loin into 1-inch cubes. Dice the peppers, onion, and pineapple into similar-sized pieces.
2. In a wok or large frying pan, heat the vegetable oil over high heat. Add the pork cubes and stir-fry until they begin to brown.
3. Add the peppers and onion to the wok. Stir-fry for another two minutes, until the vegetables are crisp-tender.
4. Add the pineapple, sugar, vinegar, and soy sauce. Stir well to combine, then reduce heat to medium and let simmer for 2-3 minutes until the sauce thickens.
5. In a small bowl, mix the cornstarch with 2 tablespoons of water to create a slurry. Slowly drizzle this into the wok, stirring constantly until the sauce thickens.
6. Serve the stir-fried pork over steamed rice for a complete meal.
