Rinse the beef and cut it into cubes about 3/4 inch (1.5–2 cm) in size. Marinate with 2 teaspoons seasoning powder, 1/2 tablespoon soy sauce, 1 tablespoon garlic water, and 1/2 tablespoon vegetable oil.

Cut the bell peppers, onion, and tomato into bite-sized cubes about 3/4 inch (2 cm). Sauté some garlic with a little oil in a pan until fragrant, then add the vegetables and stir-fry until just cooked. Transfer the vegetables to a plate.

Add the remaining garlic and black pepper to the pan and sauté until fragrant. Add the beef and stir-fry quickly over high heat until the beef is seared. Add 1 tablespoon ketchup, 1 tablespoon soy sauce, 1 tablespoon chili sauce (omit if serving children), and 2 teaspoons sugar. Return the sautéed vegetables to the pan and stir everything together so the sauce coats the beef. Cook over medium heat for about 10–15 minutes. Add 1 tablespoon red wine, stir well, and turn off the heat. If the beef is cut small, it will be tender even after just 10 minutes of cooking.

Serve the cooked beef with fried bread. Enjoy!
