For the steak, combine the ribeye or sirloin steak with 1 tbsp fish sauce, 1 tbsp soy sauce, 1 tbsp oyster sauce, 1 tbsp brown sugar, 1 tsp sesame oil, 2 minced garlic cloves, and 1 tsp black pepper. Marinate the steak for at least 30 minutes. Meanwhile, prepare the dipping sauce by combining 2 tbsp fish sauce, 1 tbsp lime juice, 1 tbsp toasted rice powder, 1 tbsp brown sugar, chopped Thai chilies, 1 tbsp sliced shallots, and fresh cilantro. Once marinated, grill or sear the steak to your preferred doneness. Let it rest, then slice it up, dip into the sauce, and enjoy!
