Creating Crying Tiger Beef is straightforward. Follow these steps for a delightful dish:

1. Prepare Marinade: In a bowl, combine soy sauce, fish sauce, lime juice, brown sugar, minced garlic, and black pepper. Mix until well combined.
2. Marinate Beef: Place the sliced beef into the marinade, ensuring all pieces are coated. Cover and refrigerate for 30 minutes.
3. Make Dipping Sauce: In a small bowl, whisk together fish sauce, lime juice, sugar, minced chilies, and minced garlic. Set aside.
4. Heat Oils: In a large skillet or grill pan, heat vegetable oil and sesame oil over medium-high heat.
5. Cook Beef: Remove beef from the marinade, allowing excess marinade to drip off. Cook the beef in the hot skillet for about 3-4 minutes on each side, or until cooked to your desired doneness.
6. Garnish: Once cooked, remove from heat and let it rest for a few minutes. Then, slice the beef into bite-sized pieces.
7. Serve: Arrange the beef on a serving platter, garnishing with fresh cilantro and cucumber slices. Serve with the dipping sauce on the side.
