Sweet and sour vegetable skewers are a tasty and tangy dinner option. Use a combination of vegetables like bell peppers, pineapple chunks, red onions, and carrots. Make a sweet and sour sauce using ingredients like soy sauce, vinegar, brown sugar, and ketchup. Toss the vegetables in the sauce and thread them onto skewers. Grill the skewers until the vegetables are tender and slightly caramelized. Serve these flavorful skewers over a bed of steamed rice for a delicious sweet and sour dinner.
