Choose the leaves of piper lolot off the stems. Remove the stalks, wash and dry.
Mix in a bowl. mix ground pork, ground beef as well as the other ingredients needed to make the beef rolls (minced the lemongrass and shallots garlic salt, pepper soy sauce as well as olive oil and fish sauce). Mix thoroughly to mix. It is possible to simmer one teaspoon of the filling to check whether it's seasoned to your taste.
Lay a piper-lolot leaf (or two leaves if the size is small) on a clean , flat surface. Add approximately a tablespoon of meat filling onto the leaf, shape into a small sized log and then wrap the leaf around it.
Thread 3-4 beef rolls on the toothpick or on a skewer to ensure the leaves in the right place.
Set up a grill pan on moderate temperature (or make use of the outdoor grill). Lightly rub the rolls with oil. When you have the pan heated then add the beef roll.
Cook for around one minute to cook till the leaves have softened on the bottom. Turn and cook the second side. The toothpicks can be removed (or skewers) after the leaves have cooked in both directions.
Grill for a few hours until filling has cooked. Then rotate the rolls and adjust the heat as necessary to ensure that the leaves are not charred excessively.
While you grill the rolls while grilling, add rice vinegar as well as honey and fish sauce to a small saucepan at medium-low heat to create the sauce for dipping. When the sauce begins slowing down, move it it into an ice cube and add minced garlic and bird's-eye chili. Check the flavor and adjust it according to your preference.
Serve the beef roll immediately with the sauce for dipping vermicelli noodles and lettuce, the herbs, and the Roasted peanuts.
