Cut the beef steak into bite-sized cubes and let it sit at room temperature for an hour.

Season the beef with salt and pepper. Use herb salt if available.

Slice garlic thinly and chop onion and bell pepper into similar-sized pieces as the beef.

Prepare the sauce by mixing steak sauce, ketchup, oyster sauce, and corn syrup.

Heat butter in a pan and sauté garlic until fragrant and golden.

Add onion and bell pepper to the pan and cook until partially softened.

Add the seasoned beef to the pan and cook quickly over high heat.

Once the beef loses its red color, add the prepared sauce and stir-fry quickly.
