In a bowl, mix together the garlic, lime juice, fish sauce, Lee Kum Kee Panda Brand Cooking Soy Sauce, Lee Kum Kee Lime Cilantro Flavored Hoisin Sauce, brown sugar, lemongrass paste, and 1 tablespoon of the vegetable oil.
Heat 1 tablespoon of the vegetable oil in a large pan over high heat. Add half of the brisket to the pan and spread it out in a single layer. Cook for about 1 minute then flip the brisket over onto the other side. Cook for 30 seconds then remove the brisket from the pan. Repeat this step to cook the remaining brisket.
