For all the vegetarians out there, this recipe offers a meat-free twist on the classic Hong Kong-style sweet and sour chicken. Instead of using chicken, it features tofu as the main ingredient. The tofu is marinated in a mixture of soy sauce, ginger, and garlic, then pan-fried until golden and crispy. The sweet and sour sauce is made with vinegar, sugar, ketchup, and pineapple juice, just like the original version. The result is a delicious vegetarian dish that is packed with flavor and texture. Serve it with steamed rice or noodles for a complete meal that will satisfy both vegetarians and meat-lovers alike.
